DS34C87T
CMOS Quad TRI-STATE Differential Line Driver
General Description
The DS34C87T is a quad differential line driver designed for
digital
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.
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 compatible to the DS3487T.
All inputs are protected against damage due to electrostatic
discharge by diodes to V
