Product Summary

The MAX3085ECSA is a ±15kV electrostatic discharge (ESD)-protected, high-speed transceiver for RS- 485/RS-422 communication that contain one driver and one receiver. The MAX3085ECSA features fail-safe circuitry, which guarantees a logic-high receiver output when the receiver inputs are open or shorted. This means that the receiver output will be a logic high if all transmitters on a
terminated bus are disabled (high impedance). Applications include RS-422/RS-485 Communications, Level Translators, Transceivers for EMI-Sensitive Applications and Industrial-Control Local Area Networks.

Parametrics

MAX3085ECSA absolute maximum ratings: (1)Driver Input Voltage (DI): -0.3V to (VCC + 0.3V); (2)Driver Output Voltage (A, B, Y, Z): ±13V; (3)Receiver Input Voltage (A, B): ±13V; (4)Receiver Input Voltage, Full Duplex (A, B): ±25V; (5)Receiver Output Voltage (RO): -0.3V to (VCC + 0.3V); (6)Supply Voltage (VCC): +7V; (7)Control Input Voltage (RE, DE): -0.3V to (VCC + 0.3V; (8)Storage Temperature Range: -65℃ to +150℃; (9)Lead Temperature (soldering, 10s): +300℃.

Features
