ST485B ST485C
Low power RS-485/RS-422 transceiver
Features
■ Low quiescent current: 300 µA ■ Designed for RS-485 interface application ■ - 7 V to 12 V common mode input
voltage range ■ Driver maintains high impedance in 3-state or
with the power OFF ■ 70 mV typical input hysteresis ■ 30 ns propagation delay, 5 ns skew ■ Operate from a single 5 V supply ■ Current limiting and thermal shutdown for
driver overload protection ■ Allows up to 64 transceivers on the bus
Description
The ST485 is al low power transceiver for RS-485 and RS-422 communication.
Each part contains one driver and one receiver.
This transceiver draw 300 µA (typ.
) of supply current when unloaded or fully loaded with disabl...
