DS8922/DS8922A/DS8923A TRI-STATE RS-422 Dual Differential Line Driver and Receiver Pairs June 1998 DS8922/DS8922A/DS8923A TRI-STATE® RS-422 Dual Differential Line Driver and Receiver Pairs General Description The DS8922/22A and DS8923A are Dual Differential Line Driver and Receiver pairs.
These devices are designed specifically for applications meeting the ST506, ST412 and ESDI Disk Drive Standards.
In addition, the devices meet the requirements of the EIA Standard RS-422.
These devices 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.
An input fail-safe cir...
