DS9638
RS-422 Dual High Speed Differential Line Driver
General Description
The DS9638 is a Schottky, TTL compatible, dual differential
line driver designed specifically to meet the EIA Standard
RS-422 specifications. It is designed to provide unipolar
differential drive to twisted pair or parallel wire transmission
lines. The inputs are TTL compatible. The outputs are similar
to totem pole TTL outputs, with active pull-up and pull-down.
The device features a short circuit protected active pull-up
with low output impedance and is specified to drive 50Ω
transmission lines at high speed. The mini-DIP provides high
package density.
