www.ti.com SNLS376B – MAY 1998 – REVISED APRIL 2013 DS34C87T CMOS Quad TRI-STATE Differential Line Driver
Check for Samples: DS34C87T FEATURES DESCRIPTION The DS34C87T is a quad differential line driver
designed for digital data transmission over balanced
lines. The DS34C87T meets all the requirements of
EIA standard RS-422 while retaining the low power
characteristics of CMOS. This enables the
construction of serial and terminal interfaces while
maintaining minimal power consumption. 1 2 TTL Input Compatible
Typical Propagation Delays: 6 ns
Typical Output Skew: 0.5 ns
Outputs Won't Load Line When VCC = 0V
Meets the Requirements of EIA Standard RS422
Operation from Single 5V Supply
TRI-STATE Outputs for Connection to System
Buses
Low Quiescent Current
Available in Surface Mount The DS34C87T accepts TTL or CMOS input levels
and translates these to RS-422 output levels. This
part uses special output circuitry that enables the
individual drivers to power down without loading down
the bus. This device has separate enable circuitry for
each pair of the four drivers. The DS34C87T is pin …
