DS8921/DS8921A/DS8921AT

Differential Line Driver and Receiver Pair

The DS8921, DS8921A are designed to be compatible with

TTL and CMOS.

General Description

The DS8921, DS8921A are Differential Line Driver and Re-

ceiver pairs designed specifically for applications meeting

the ST506, ST412 and ESDI Disk Drive Standards. In addi-

tion, these devices meet the requirements of the EIA Stan-

dard RS-422.

Features

n 12 ns typical propagation delay

n Output skew - 0.5 ns typical

n Meet the requirements of EIA Standard RS-422

n Complementary Driver Outputs

n High differential or common-mode input voltage ranges

The DS8921, DS8921A receivers offer an input sensitivity of

200 mV over a 7V common mode operating range. Hyster-

esis is incorporated (typically 70 mV) to improve noise mar-

gin for slowly changing input waveforms.

of 7V

0.2V receiver sensitivity over the input voltage range

The DS8921, DS8921A drivers are designed to provide uni-

polar 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.

n Receiver input hysteresis-70 mV typical

n DS8921AT industrial temperature

operation: (−40˚C to +85˚C)
