description
The uA9639C 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. It utilizes Schottky circuitry and has TTL-compatible
outputs. The inputs are compatible with either a single-ended or a differential-line system. This device operates
from a single 5-V power supply and is supplied in an 8-pin, dual-in-line package.
The uA9639C is characterized for operation from 0°C to 70°C.
