description
The uA9636AC is a dual, single-ended line driver designed to meet ANSI Standards EIA/TIA-423-B and
EIA/TIA-232-E and ITU Recommendations V.10 and V.28. The slew rates of both amplifiers are controlled by
a single external resistor, R
(WS)
, connected between the wave-shape-control (W-S) terminal and GND. Output
current limiting is provided. Inputs are compatible with TTL and CMOS and are diode protected against negative
transients. This device operates from
12 V and is supplied in an 8-pin package.
The uA9636AC is characterized for operation from 0
C to 70
C.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: All voltage values are with respect to the network ground terminal.

All typical values are at VCC =

C.
The algebraic convention, in which the less-positive (more-negative) limit is designated as minimum, is used in this data sheet for logic voltage
levels, e.g., when 5 V is the maximum, the minimum is a more-negative voltage.
Not more than one output should be shorted to ground at a time.
