DS8922/DS8922A/DS8923A TRI-STATE^®

RS-422 Dual Differential Line Driver and Receiver Pairs

Power up/down circuitry is featured which will TRI-STATE

the outputs and prevent erroneous glitches on the transmis-

sion lines during system power up or power down operation.

General Description

The DS8922/22A and DS8923A are Dual Differential Line

Driver and Receiver pairs. These devices are designed spe-

The DS8922/22A and DS8923A are designed to be compat-

cifically for applications meeting the ST506, ST412 and

ible with TTL and CMOS.

ESDI Disk Drive Standards. In addition, the devices meet the

requirements of the EIA Standard RS-422.

Features

These devices offer an input sensitivity of 200 mV over a

n 12 ns typical propagation delay

7V common mode operating range. Hysteresis is incorpo-

n Output skew — 0.5 ns typical

n Meets the requirements of EIA Standard RS-422

n Complementary Driver Outputs

rated (typically 70 mV) to improve noise margin for slowly

changing input waveforms. An input fail-safe circuit is pro-

vided such that if the receiver inputs are open the output as-

sumes the logical one state.

n High differential or common-mode input voltage ranges

The DS8922A and DS8923A drivers are designed to provide

unipolar differential drive to twisted pair or parallel wire trans-

mission lines. Complementary outputs are logically ANDed

and provide an output skew of 0.5 ns (typ.) with propagation

delays of 12 ns.

of 7V

0.2V receiver sensitivity over the input voltage range

n Receiver input fail-safe circuitry

n Receiver input hysteresis — 70 mV typical

n Glitch free power up/down

Both devices feature TRI-STATE outputs. The DS8922/22A

have independent control functions common to a driver and

receiver pair. The DS8923A has separate driver and receiver

control functions.
