3 Description

The uA9637A is a dual differential line receiver

designed to meet ANSI Standards EIA/TIA-422-B

and EIA/TIA-423-B and ITU Recommendations V.10

and V.11. The line receiver uses Schottky circuitry,

and has TTL-compatible outputs. The inputs are

compatible with either a single-ended or a differentialline

system. This device operates from a single 5V

power supply and is supplied in an 8-pin dual-in-line

package or small-outline package.

The uA9637A is characterized for operation from 0°C

to 70°C.
