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
