DS55113 DS75113 Dual TRI-STATE
Differential Line Driver
General Description
The DS55113 DS75113 dual differential line drivers with
TRI-STATE outputs are designed to provide all the features
of the DS55114 DS75114 line drivers with the added fea-
ture of driver output controls There are individual controls
for each output pair as well as a common control for both
output pairs When an output control is low the associated
output is in a high-impedance state and the output can nei-
ther drive nor load the bus This permits many devices to be
connected together on the same transmission line for party-
line applications
The output stages are similar to TTL totem-pole outputs but
with the sink outputs YS and ZS and the corresponding
active pull-up terminals YP and ZP available on adjacent
package pins
