Overview
UTC1062 LOW VOLTAGE TELEPHONE TRANSMISSION CIRCUIT WITH DIALLER INTERFACE DESCRIPTION LI NEAR I NTEGRATED CI RCUI T The UTC1062 is a bipolar integrated circuit performing all speech and line interface function required in the fully electronic telephone sets.
It performs electronic switching between dialing speech.
The circuit is able to operate down to d.
c.
line voltage of 1.
6v (with reduced performance) to facilitate the use of more telephone sets in parallel.
FEATURES * Low d.
