19-0626; Rev 0; 1/07 KIT ATION EVALU E L B AVAILA 6-Channel High-Speed Logic-Level Translators The MAX13030E-MAX13035E 6-channel, bidirectional level translators provide the level shifting necessary for 100Mbps data transfer in multivoltage systems. The MAX13030E-MAX13035E are ideally suited for memory-card level translation, as well as generic level translation in systems with six channels. Externally applied voltages, VCC and VL, set the logic levels on either side of the device. Logic signals present on the VL side of the device appear as a higher voltage logic signal on the V CC side of the device and vice versa. The MAX13035E features a CLK_RET output that returns the same clock signal applied to the CLK_VL input. The MAX13030E-MAX13035E operate at full speed with external drivers that source as little as 4mA output current. Each I/O channel is pulled up to VCC or VL by an internal 30A current source, allowing the MAX13030E-MAX13035E to be driven by either pushpull or open-drain drivers. The MAX13030E-MAX13034E feature an enable (EN) input that places the device into a low-power shutdown mode when driven low. The MAX13030E-MAX13035E features an automatic shutdown mode that disables the part when VCC is less than VL. The state of I/O VCC_ and I/O VL_ during shutdown is chosen by selecting the appropriate part version (see Ordering Information/ Selector Guide). The MAX13030E-MAX13035E accept V CC voltages from +2.2V to +3.6V and VL voltages from +1.62V to +3.2V, making them ideal for data transfer between low-voltage ASIC/PLDs and higher voltage systems. The MAX13030E-MAX13035E are available in 16-bump UCSP (2mm x 2mm) and 16-pin TQFN (4mm x 4mm) packages, and operate over the extended -40C to +85C temperature range.

The MAX13030E-MAX13035E are ideally suited for memory card level translation, as well as generic level translation in systems with six channels. Externally applied voltages, VCC and VL, set the logic levels on either side of the device. Logic signals present on the VL side of the device appear as a higher voltage logic signal on the VCC side of the device, and vice versa. The MAX13035E features a CLK_RET output that returns the same clock signal applied to the CLK_VL input. The MAX13030E-MAX13035E operate at full speed with external drivers that source as little as 4mA output current. Each I/O channel is pulled up to VCC or VL by an internal 30A current source, allowing the MAX13030E-MAX13035E to be driven by either pushpull or open-drain drivers. The MAX13030E-MAX13034E feature an enable (EN) input that places the device into a low-power shutdown mode when driven low. The MAX13030E-MAX13035E features an automatic shutdown mode that disables the part when VCC is less than VL. The state of I/O VCC_ and I/O VL_ during shutdown is chosen by selecting the appropriate part version (see Ordering Information/ Selector Guide). The MAX13030E-MAX13035E accept VCC voltages from +2.2V to +3.6V and VL voltages from +1.62V to +3.2V. Level Translation For proper operation, ensure that +2.2V VCC +3.6V, and +1.62V VL VCC - 0.2V. When power is supplied to V L while V CC is either missing or less than V L , the MAX13030E-MAX13035E automatically enters a low- power mode. In addition, the MAX13030E- MAX13034E enters a low-power mode if EN = 0V. This allows VCC to be disconnected and still have a known state on I/O VL_. The maximum data rate depends heavily on the load capacitance (see the Typical Operating Characteristics Rise/Fall Times), output impedance of the driver, and the operating voltage range. Input Driver Requirements The MAX13030E-MAX13035E architecture is based on an nMOS pass gate and output accelerator stages (see Figure 6). Output accelerator stages are always in tristate mode except when there is a transition on any of the translators on the input side, either I/O VL_, CLK_VL, I/O VCC_, or CLK_VCC. A short pulse is then generated during which the output accelerator stages become active and charge/discharge the capacitances at the I/Os. Due to its architecture, both input stages become 12 VCC VL ENABLE ENABLE ENABLE 30A 30A I/O VL_ I/O VCC_ VCC VL BOOST CIRCUIT VL VCC BOOST CIRCUIT NOTES: 1) THE MAX13030E-MAX13034E ARE ENABLED WHEN VL < VCC - 0.2V AND EN = VL. 2) THE MAX13035E IS ENABLED WHEN VL < VCC - 0.2V. Figure 6. Simplified Functional Diagram for One I/O Line active during the one-shot pulse. This can lead to some current feeding into the external source that is driving the translator. However, this behavior helps to speed up the transition on the driven side. The MAX13030E-MAX13035E have internal current sources capable of sourcing 30A to pullup the I/O lines. These internal pullup current sources allow the inputs to be driven with open-drain drivers, as well as push-pull drivers. It is not recommended to use external pullup resistors on the I/O lines. The architecture of the MAX13030E-MAX13035E permit either side to be driven with a minimum of 4mA drivers or larger. Output Load Requirements The MAX13030E-MAX13035E I/O are designed to drive CMOS inputs. Do not load the I/O lines with a resistive load less than 25k and do not place an RC circuit at the input of these devices to slow down the edges. If a slower rise/fall time is required, refer to the MAX3000E/ MAX3001E logic-level translator datasheet. For I 2C level translation, refer to the MAX3372E-MAX3379E/ MAX3390E-MAX3393E datasheet. Shutdown Mode The MAX13030E-MAX13034E feature an enable (EN) input that places the device into a low-power shutdown mode when driven low. The MAX13030E-MAX13035E features an automatic shutdown mode that disables the part when VCC is missing or less than VL. ______________________________________________________________________________________ 6-Channel High-Speed Logic-Level Translators Open-Drain Signaling The MAX13030E-MAX13035E are designed to pass open-drain as well as CMOS push-pull signals. When used with open-drain signaling, the rise time is dominated by the interaction of the internal pullup current source and the parasitic load capacitance. The MAX13030E-MAX13035E include internal rise time accelerators to speed up transitions, eliminating any need for external pullup resistors. Application Information Layout Recommendations Use standard high-speed layout practices when laying out a board with the MAX13030E-MAX13035E. For example, to minimize line coupling, place all other signal lines not connected to the MAX13030E-MAX13035E at least 1x the substrate height of the PCB away from the input and output lines of the MAX13030E-MAX13035E. Power-Supply Decoupling To reduce ripple and the chance of introducing data errors, bypass VL and VCC to ground with 0.1F ceramic capacitors. Place all capacitors as close as possible to the power-supply inputs. For full ESD protection, bypass VCC with a 1F ceramic capacitor located as close as possible to the VCC input. Unidirectional vs. Bidirectional Level Translator The MAX13030E-MAX13035E bidirectional level translators can operate as a unidirectional device to translate signals without inversion. These devices provide the smallest solution (UCSP package) for unidirectional level translation without inversion. SD Card Detection SD, MiniSD, MMC and similar types of cards provide detection of a card through a pullup resistor on one of the DAT lines, or by use of a mechanical switch. This pullup resistor is internal to the memory card itself. The MAX13030E-MAX13035E only support detection of a memory card through a mechanical switch, and it is recommended that the internal resistor for card detection be switched off by the command interface. For example, when using SD cards, the command SET_CLR_CARD_DETECT (ACMD42) disables this resistor.

Use with External Pullup/Pulldown Resistors Due to the architecture of the MAX13030E- MAX13035E, it is not recommended to use external pullup or pulldown resistors on the bus. In certain applications, the use of external pullup or pulldown resistors is desired to have a known bus state when there is no active driver on the bus. For example, this may happen when interfacing to a memory card slot with no memory card inserted. The MAX13030E-MAX13035E include internal pullup current sources that set the bus state when the device is enabled. In shutdown mode, the state of I/O V CC_ and I/O V L_ is dependent on the selected part version (see Ordering Information/ Selector Guide for further information).

CLK_V L and CLK_VCC are identical to the other I/O channels, the only difference being that CLK_VCC is internally tied to the VCC side of CLK_RET (see the Functional Diagram). 6-Channel High-Speed Logic-Level Translators MAX13030E-MAX13035E Functional Diagram VL VL VCC VCC MAX13035E MAX13030E- MAX13034E I/O VL1 I/O VCC1 I/O VL1 I/O VCC1 I/O VL2 I/O VCC2 I/O VL2 I/O VCC2 I/O VL3 I/O VCC3 I/O VL3 I/O VCC3 I/O VL4 I/O VCC4 I/O VL4 I/O VCC4 I/O VL5 I/O VCC5 I/O VL5 I/O VCC5 I/O VL6 I/O VCC6 CLK_ VL CLK_ VCC EN GND CLK_RET GND 14 ______________________________________________________________________________________ 6-Channel High-Speed Logic-Level Translators I/O VL6 EN I/O VL5 I/O VL4 TOP VIEW 12 11 10 9 TOP VIEW (BUMPS ON BOTTOM) 1 + GND 13 8 I/O VCC5 I/O VCC6 14 7 I/O VCC4 6 I/O VCC3 5 I/O VCC2 MAX13030E- MAX13034E I/O VCC1 15 VCC *EP 16 2 3 4 MAX13030E-MAX13034E A I/O VL3 I/O VCC3 I/O VCC4 I/O VL4 I/O VL2 I/O VCC2 I/O VCC5 I/O VL5 VL VCC GND EN I/O VL1 I/O VCC1 I/O VCC6 I/O VL6 B 1 2 3 4 I/O VL1 VL I/O VL2 I/O VL3 C + D 16 TQFN (4mm x 4mm) *CONNECT EXPOSED PADDLE TO GROUND 16 UCSP (2mm x 2mm) CLK_VL CLK_RET I/O VL5 I/O VL4 TOP VIEW 12 11 10 9 TOP VIEW (BUMPS ON BOTTOM) 1 + GND 13 8 I/O VCC5 CLK_VCC 14 7 I/O VCC4 6 I/O VCC3 5 I/O VCC2 MAX13035E I/O VCC1 15 VCC *EP 16 2 3 4 MAX13035E A I/O VL3 I/O VCC3 I/O VCC4 I/O VL4 I/O VL2 I/O VCC2 I/O VCC5 I/O VL5 VL VCC GND CLK_RET I/O VL1 I/O VCC1 CLK_VCC CLK_VL B 1 2 3 4 I/O VL1 VL I/O VL2 I/O VL3 C + 16 TQFN (4mm x 4mm) D *CONNECT EXPOSED PADDLE TO GROUND 16 UCSP (2mm x 2mm) ______________________________________________________________________________________ 15 MAX13030E-MAX13035E Pin Configurations 6-Channel High-Speed Logic-Level Translators MAX13030E-MAX13035E Typical Operating Circuits (continued) +3.3V +1.8V 0.1F VL +1.8V SYSTEM CONTROLLER 1F 0.1F VCC +3.3V SYSTEM MAX13030E- MAX13034E EN I/O VL_ EN DATA I/O VCC_ 6 DATA 6 GND GND GND Ordering Information/Selector Guide (continued) PIN-PACKAGE I/O VL_ STATE DURING SHUTDOWN MAX13031EEBE+* 16 UCSP High impedance 16.5k to VCC B16-1 MAX13031EETE+* 16 TQFN-EP** High impedance 16.5k to VCC T1644-4 MAX13032EEBE+ 16 UCSP High impedance 16.5k to GND B16-1 MAX13032EETE+ 16 TQFN-EP** High impedance 16.5k to GND T1644-4 MAX13033EEBE+* 16 UCSP 16.5k to GND High impedance B16-1 MAX13033EETE+* 16 TQFN-EP** 16.5k to GND High impedance T1644-4 MAX13034EEBE+* 16 UCSP 16.5k to GND 16.5k to GND B16-1 MAX13034EETE+* 16 TQFN-EP** 16.5k to GND 16.5k to GND T1644-4 MAX13035EEBE+ 16 UCSP 75k to VL High impedance B16-1 MAX13035EETE+ 16 TQFN-EP** 75k to VL High impedance T1644-4 PART I/O VCC_ STATE DURING SHUTDOWN Note: All devices are specified over the -40C to +85C operating temperature range. +Denotes a lead-free package. **EP = Exposed paddle. 16 ______________________________________________________________________________________ PKG CODE 6-Channel High-Speed Logic-Level Translators 16L,UCSP.EPS PACKAGE OUTLINE, 4x4 UCSP 21-0101 H 1 1 ______________________________________________________________________________________ 17 MAX13030E-MAX13035E Package Information (The package drawing(s) in this data sheet may not reflect the most current specifications.
