RS-422 Dual High Speed Differential Line Driver
General Description
The DS9638isa Schottky,TTL compatible, dual differential
line driver designed specificallyto meettheEIA Standard
RS-422 specifications.Itis designedto provide unipolardif-
ferential driveto twistedpairor parallel wire transmission
lines.The inputs areTTLcompatible. Theoutputsare similar totem poleTTL outputs, with active pull-upand pull-down.
The device featuresa short circuit protected active pull-up
withlow output impedance andis specifiedto drive 50Ω
transmissionlinesat high speed. Themini-DIP provides high
package density.
Features Single5V supply Schottky technology TTLand CMOS compatible inputs Output short circuit protection Input clamp diodes Complementary outputs Minimum output skew (<1.0ns typical)50mA output drive capabilityfor 50Ω transmission lines MeetsEIA RS-422 specifications Propagation delayof less than10ns “Glitchless” differential output Delay time stable with VCCand temperature variations
(<2.0ns typical) (Figure3) Extended temperature range
