3 Description

The DS8921, DS8921A, and DS8921AT devices are

differential line driver and receiver pairs designed specifically for applications meeting the ST506,

ST412, and ESDI disk drive standards. In addition,

these devices meet the requirements of the EIA

standard RS-422.

The DS8921x receivers offer an input sensitivity of

200 mV over a ±7 V common mode operating range.

Hysteresis is incorporated (typically 70 mV) to

improve noise margin for slowly changing input

waveforms.

The DS8921x drivers are designed to provide

unipolar differential drive to twisted-pair or parallel

wire transmission lines. Complementary outputs are

logically ANDed and provide an output skew of 0.5 ns

(typical) with propagation delays of 12 ns.

The DS8921x devices are designed to be compatible

with TTL and CMOS.
