IL34C87
CMOS Quad TRISTATE Differential Line Driver.
General Description
The IL34C87T is a quad differential line driver
designed for digital data transmission over balanced
lines. The IL34C87T 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. The
IL34C87T 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. All inputs
are protected against damage due to electrostatic
discharge by diodes to V_CC and ground.
