MAX491ECSD+T Overview

The MAX491ECSD+T is a ±15KV ESD protected, low power RS485/RS422 transceiver in 14 pin NSOIC package. This device is used as a low power transceiver for RS485 and RS422 communications in harsh environments. The driver output and receiver input is protected against ±15KV electro static discharge (ESD) shocks without latch-up. The slew rate is not limited allowing it to transmit up to 2.5Mbps. The driver is short circuit current limited and is protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high impedance state. It features fail-safe circuitry which has a logic high receiver output when the receiver input is open.


Features

 Supply voltage range from 4.75V to 5.25V

 Operating temperature range from 0°C to 70°C

 Designed for full duplex communication

 Features receiver/driver enable function

 Quiescent current is 300µA

 Allows up to 32 transceivers on the bus
