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 circuit is provided
such that if the receiver inputs are open the output
assumes the logical one state.
