ST485ER

±15KV ESD protected, Low power

RS-485/RS-422 transceiver

General features

■ Low quiescent current: 300µA

■ Designed for RS-485 interface application

■ -7V to 12V common mode input voltage range

■ Driver maintains high impedance in 3-state or

with the power OFF

■ 70mV tipycal input hysteresis

■ 30ns propagation delay, 5ns skew

■ Operate from a single 5V supply

■ Current limiting and thermal shutdown for

driver overload protection

■ ESD protection:

– ±15KV (H.B.M.)

– ±8KV (IEC-1000-4-2 contact discharge)

■ Allows up to 256 transceivers on the bus

Description

The ST485E is al low power transceiver for RS-

485 and RS-422 communication. Each driver

output and receiver input is protected against

±15KV electrostatic discharge (H.B.M.) ±8KV

(IEC-1000-4-2 contact discharge) shocks, without

latchup. These parts contain one driver and one

receiver.

This transceiver draws 300µA (typ.) of supply

current when unloaded or fully loaded with

disabled drivers.

It operates from a single 5V supply.

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.

The ST485E is designed for bi-directional data

communications on multipoint bus transmission

line (half-duplex applciations).
