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
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.

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.
