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.
