MAX3079E - Maxim Integrated

MAX3079E RS-485/RS-422 Transceivers

The MAX3070E–MAX3079E 3.3V, ±15kV ESD-protected, RS-485/RS-422 transceivers feature one driver and one receiver. These devices include fail-safe circuitry, guaranteeing a logic-high receiver output when receiver inputs are open or shorted. The receiver outputs a logic-high if all transmitters on a terminated bus are disabled (high impedance). The devices inc.

Features

independently programmable receiver and transmitter output phase through separate pins. The MAX3070E
  –MAX3079E transceivers draw 800μA of supply current when unloaded, or when fully loaded with the drivers disabled. All devices have a 1/8-unit load receiver input impedance, allowing up to 256 transceivers on the bus. Applications
