DS9636A
RS-423 Dual Programmable Slew Rate Line Driver
General Description
The DS9636A is a TTL/CMOS compatible, dual, single
ended line driver which has been specifically designed to
satisfy the requirements of EIA Standard RS-423.
The DS9636A is suitable for use in digital data transmission
systems where signal wave shaping is desired. The output
slew rates are jointly controlled by a single external resistor
connected between the wave shaping control lead (WS) and
ground. This eliminates any need for external filtering of the
output signals. Output voltage levels and slew rates are in-
dependent of power supply variations. Current-limiting is
provided in both output states. The DS9636A is designed for
nominal power supplies of
