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

Inputs are TTL compatible with input current loading low

enough (1/10 UL) to be also compatible with CMOS logic.

Clamp diodes are provided on the inputs to limit transients

below ground.
