www.ti.com SNLS389D – MAY 1998 – REVISED APRIL 2013 DS9638 RS-422 Dual High Speed Differential Line Driver
Check for Samples: DS9638 FEATURES 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 pulldown. The device features a short circuit protected
active pull-up with low output impedance and is
specified to drive 50О© transmission lines at high
speed. The mini-DIP provides high package density. 1 2 Single 5V Supply
