General Description

The DS8922/22A and DS8923A are Dual Differential Line
Driver and Receiver pairs. These devices are designed spe-
cifically for applications meeting the ST506, ST412 and
ESDI Disk Drive Standards.In addition,the devices meetthe
requirementsofthe EIA Standard RS-422.
These devices offeran input sensitivityof 200 mV overa
±7V common mode operating range. Hysteresisis incorpo-
rated (typically70 mV)to improve noise marginfor slowly
changing input waveforms.An input fail-safe circuitis pro-
vided such thatif the receiver inputs are open the output
assumes the logical one state.
The DS8922A and DS8923A drivers are designedto provide
unipolar differential driveto twisted pairor parallel wire trans-
mission lines. Complementary outputs are logically ANDed
and providean output skewof0.5ns (typ.) with propagation
delaysof12ns.
Both devices feature TRI-STATE outputs. The DS8922/22A
have independent control functions commontoa driver and
receiver pair. The DS8923A has separate driver and receiver
control functions.
Power up/down circuitryis featured which will TRI-STATE
the outputs and prevent erroneous glitchesonthe transmis-
sion lines during system powerupor power down operation.
The DS8922/22A and DS8923Aare designedtobe compat-
ible with TTL and CMOS.
