DS9638 - RS-422 Dual High Speed Differential Line Driver

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.

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. Features Single 5V supply Schottky technology TTL and CMOS compatible inputs Output short circuit protection Input clamp diodes Complementary outputs Minimum output skew ( < 1.0 ns typical) 50 mA output drive capability for 50Ω transmission lines Meets EIA RS-422 specifications Propagation delay of less than 10 ns “Glitchl.

DS9638 RS-422 Dual High Speed Differential Line Driver May 1998 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.
