Overview

DS8921/DS8921A/DS8921AT Differential Line Driver and Receiver Pair May 1998 DS8921/DS8921A/DS8921AT Differential Line Driver and Receiver Pair General Description The DS8921, DS8921A 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 DS8921, DS8921A receivers offer an input sensitivity of 200 mV over a ± 7V common mode operating range.
Hysteresis is incorporated (typically 70 mV) to improve noise margin for slowly changing input waveforms.
The DS8921, DS8921A drivers are designed to provide unipolar differential drive t...
