ST485EB

ST485EC - ST485EX

±15 kV ESD protected, 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

■ Operates from a single 5 V supply

■ Current limiting and thermal shutdown for

driver overload protection

■ ESD protection:

– ±15 kV (H.B.M.)

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

■ Allows up to 256 transceivers on the bus

Description

The ST485E is a low power transceiver for RS-

485 and RS-422 communication. Each driver

output and receiver input is protected against

±15 kV electrostatic discharge (H.B.M.) (ESD)

shocks, without latch-up. These parts contain one

driver and one receiver in half duplex

configuration.

This transceiver draws 300 µA (typ.) of supply

current when unloaded or fully loaded with

disabled drivers.

It operates from a single 5 V supply.

Driver is short-circuit current limited and is

protected against excessive power dissipation by

thermal shutdown circuitry that place the driver

outputs into a high-impedance state.

The ST485E is designed for bi-directional data

communications on multipoint bus transmission

lines (half-duplex applications).
