FEATURES
DESCRIPTION
The DS34C87T is a quad differential line driver
2
TTL Input Compatible
designed for digital data transmission over balanced
Typical Propagation Delays: 6 ns
lines. The DS34C87T meets all the requirements of
Typical Output Skew: 0.5 ns
EIA standard RS-422 while retaining the low power
characteristics
of
CMOS.
This
enables
the
Outputs Won't Load Line When VCC = 0V
construction of serial and terminal interfaces while
Meets the Requirements of EIA Standard RS-
maintaining minimal power consumption.
422
The DS34C87T accepts TTL or CMOS input levels
Operation from Single 5V Supply
and translates these to RS-422 output levels. This
TRI-STATE Outputs for Connection to System
part uses special output circuitry that enables the
Buses
individual drivers to power down without loading down
the bus. This device has separate enable circuitry for
Low Quiescent Current
each pair of the four drivers. The DS34C87T is pin
Available in Surface Mount
compatible to the DS3487T.
All inputs are protected against damage due to
electrostatic discharge by diodes to VCC and ground.
