IDT74ALVCF162835A 3.3V CMOS 18-BIT UNIVERSAL BUS DRIVER WITH 3-STATE OUTPUTS INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS 18-BIT UNIVERSAL BUS DRIVER WITH 3-STATE OUTPUTS IDT74ALVCF162835A DESCRIPTION: FEATURES: This 18-bit universal bus driver is built using advanced dual metal CMOS technology. Data flow from A to Y is controlled by the output-enable (OE) input. The device operates in the transparent mode when the latch-enable (LE) input is high. The A data is latched if the clock (CLK) input is held at a high or low logic level. If LE is low, the A data is stored in the latch flip-flop on the low-to-high transition of CLK. When OE is high, the outputs are in the high-impedance state. The ALVCF162835A has series resistors in the device output structure which will reduce switching noise in 128MB and 256MB SDRAM modules. Designed with a drive capability of 18mA, the ALVCF162835A is a midway drive between the ALVC162835 (12mA) and ALVC16835 (24mA). The ALVCF162835A is a faster version of the ALVCF162835 or ALVC162835. It is suitable for PC133 applications and particularly SDRAM Modules clocked at 133 MHz. * 0.5 MICRON CMOS Technology * Typical tSK(o) (Output Skew) < 250ps * ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200pF, R = 0) * VCC = 3.3V 0.3V, Normal Range * VCC = 2.7V to 3.6V, Extended Range * VCC = 2.5V 0.2V W typ. static) * CMOS power levels (0.4 * Rail-to-Rail output swing for increased noise margin * Available in TSSOP and TVSOP packages DRIVE FEATURES: * Balanced Output Drivers: 18mA * Low switching noise APPLICATIONS: * SDRAM Modules * PC Motherboards * Workstations FUNCTIONAL BLOCK DIAGRAM OE CLK LE A1 27 30 28 54 1D 3 C1 Y1 CLK TO 17 OTHER CHANNELS The IDT logo is a registered trademark of Integrated Device Technology, Inc.
