ST485ABDR Datasheet PDF - ST Microelectronics

Description

●The ST485A is a low power, high speed transceiver for RS-485 and RS-422 communications. The device contains one driver and one receiver in half duplex configuration. The ST485A draws 3 mA (typ.) of supply current when unloaded or fully loaded with disabled drivers. It operates from a single 5 V supply.

●Features

●■ Low supply current: 5 mA max

●■ High data rate > 30 Mbps

●■ Designed for RS 485 interface applications

●■ -7 to 12 common mode input voltage range

●■ Driver maintains high impedance in 3-state or with the power off

●■ 70mV typical input hysteresis

●■ Operate from single 5 supply

●■ ±4 kV ESD protection

●■ Current limiting and thermal shutdown for driver overload protection

●■ Latch-up free up to 500 mA
