ST485E

15ꢀK ESD protected, low power

RS-485/RS-422 transceiver

General features

■ Low quiescent current: 300µA

■ Designed for RS-485 interface application

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

■ Driver maintains high impedance in 3-state or

with the power OFF

■ 70mK typical input hysteresis

■ 30ns propagation delay, 5ns skew

■ Operates from a single 5K supply

DIP-8

SO-8

■ Current limiting and thermal shutdown for

driver and one receiver in half duplex

configuration.

driver overload protection

■ ESD protection:

This transceiver draws 300µA (typ.) of supply

current when unloaded or fully loaded with

disabled drivers.

–

15ꢀK (H.B.M.)

8ꢀK (IEC-1000-4-2 contact discharge)

■ Allows up to 64 transceivers on the bus

It operates from a single 5K 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.

Description

The ST485E is a low power transceiver for RS-

485 and RS-422 communication. Each driver

output and receiver input is protected against

15ꢀK electrostatic discharge (H.B.M.) (ESD)

shocks, without latch-up. These parts contain one

The ST485E is designed for bi-directional data

communications on multipoint bus transmission

lines (half-duplex applications).
