GL6962/GL6962A

Low Voltage Universal Speech Network

Description

PIN Configuration

The GL6962 and GL6962A are bipolar integrated

circuits that perform all speech and line interface

functions required in fully electronic telephone sets.

They perform electronic switching between dialing

and speech. The ICs operate at line voltage down

to 1.6V DC (with reduced performance) to

facilitate the use of more telephone sets connected

in parallel.
