Maxim MAX3074EASA

收发器RS422，RS485500kbps

Overview

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 MAX3070E–MAX3079E include a hot-swap capability to eliminate false transitions on the bus during power-up or hot insertion.

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.
