19-1779; Rev 2; 10/02 15kV ESD-Protected, 10Mbps, 3V/5V, Low-Power Quad RS-422/RS-485 Receivers ____________________________Features The MAX3093E/MAX3094E are rugged, low-power, quad, RS-422/RS-485 receivers featuring electrostatic discharge (ESD) protection for use in harsh environments. All receiver inputs are protected to 15kV using IEC 1000-4-2 Air-Gap Discharge, 8kV using IEC 10004-2 Contact Discharge, and 15kV using the Human Body Model. The MAX3093E operates from a +5V supply, while the MAX3094E operates from a +3.3V supply. Receiver propagation delays are guaranteed to within 8ns of a predetermined value, thereby ensuring device-to-device matching across production lots. The devices feature a 1nA low-power shutdown mode in which the receiver outputs are high impedance. When active, these receivers have a fail-safe feature that guarantees a logic-high output if the input is open circuit. They also have a quarter-unit-load input impedance that allows 128 receivers on a bus. The MAX3093E/MAX3094E are pin-compatible, lowpower upgrades to the industry-standard '34C86. They are available in space-saving TSSOP, narrow SO, and PDIP packages.

The MAX3093E/MAX3094E receiver inputs have extra protection against static electricity found in normal operation. Maxim's engineers have developed stateof-the-art structures to protect these pins against 15kV ESD without damage. After an ESD event, the MAX3093E/MAX3094E continue working without latchup. ESD protection can be tested in several ways. The receiver inputs are characterized for protection to the following: * 15kV using the Human Body Model * 8kV using the Contact Discharge Method specified in IEC 1000-4-2 (formerly IEC 801-2) * 15kV using the Air-Gap Method specified in IEC 1000-4-2 (formerly IEC 801-2) ESD Test Conditions ESD performance depends on a number of conditions. Contact Maxim for a reliability report that documents test setup, methodology, and results. Human Body Model Figure 4a shows the Human Body Model, and Figure 4b shows the current waveform it generates when discharged into a low impedance. This model consists of a 100pF capacitor charged to the ESD voltage of interest, which is then discharged into the device through a 1.5k resistor. IEC 1000-4-2 Since January 1996, all equipment manufactured and/or sold in the European community has been required to meet the stringent IEC 1000-4-2 specification. The IEC 1000-4-2 standard covers ESD testing and performance of finished equipment; it does not specifically refer to integrated circuits. The MAX3093E/MAX3094E help you design equipment that meets Level 4 (the highest level) of IEC 1000-4-2, without additional ESD-protection components. The main difference between tests done using the Human Body Model and IEC 1000-4-2 is higher peak current in IEC 1000-4-2. Because series resistance is lower in the IEC 1000-4-2 ESD test model (Figure 5a), the ESD-withstand voltage measured to this standard is generally lower than that measured using the Human Body Model. Figure 5b shows the current waveform for the 8kV IEC 1000-4-2 Level 4 ESD Contact Discharge test. The Air-Gap test involves approaching the device with a charge probe. The Contact-Discharge method connects the probe to the device before the probe is energized. Machine Model The Machine Model for ESD testing uses a 200pF storage capacitor and zero-discharge resistance. It mimics the stress caused by handling during manufacturing and assembly. All pins (not just RS-485 inputs) require this protection during manufacturing. Therefore, the Machine Model is less relevant to the I/O ports than are the Human Body Model and IEC 1000-4-2. Low-Power Shutdown Mode The function tables show the functionality of the enable inputs. The MAX3093E/MAX3094E enter shutdown when ENAC and ENBD are low. In shutdown, all outputs go high impedance and the devices typically draw less than 1nA. The devices exit shutdown by taking either ENAC or ENBD high. The typical shutdown exit time is 600ns.

This feature allows multiple data lines to receive data and clock signals with minimal skewing with respect to each other. The MAX3093E receiver propagation delays are trimmed to a predetermined value 8ns, while the MAX3094E delays are trimmed to a predetermined value 10ns. VCC 1k _+ 150 _- 128 Receivers on the Bus The standard RS-485 input impedance is 12k (oneunit load). The standard RS-485 transmitter can drive 32 unit loads. The MAX3093E/MAX3094E present a 1/4unit-load input impedance (48k), which allows up to 128 receivers on a bus. Any combination of these RS485 receivers with a total of 32-unit loads can be connected to the same bus. MAX3093E MAX3094E 1k Figure 6. External Fail-Safe Implementation Fail-Safe Implementation The MAX3093E/MAX3094E receiver inputs guarantee a logic high output when the inputs are open circuit (no termination resistor used). This occurs when the transmitter is removed from the bus or when all transmitter outputs are high impedance. However, when the line is terminated and the transmitters are disabled, the differential voltage between the _+ and _- inputs falls below the 200mV RS-485 sensitivity threshold. Consequently, the outputs become undefined. To maintain a failsafe receiver output while using a terminating resistor, input _+ must be biased at least 200mV above input B. The resistor-divider network shown in Figure 6 is recommended. 10 Chip Information TRANSISTOR COUNT: 676 ______________________________________________________________________________________ 15kV ESD-Protected, 10Mbps, 3V/5V, Low-Power Quad RS-422/RS-485 Receivers TSSOP4.40mm.EPS PACKAGE OUTLINE, TSSOP 4.40mm BODY 21-0066 I 1 1 ______________________________________________________________________________________ 11 MAX3093E/MAX3094E Package Information (The package drawing(s) in this data sheet may not reflect the most current specifications.
