UNIVERSAL CT–1
SUBSYSTEM
INTEGRATED CIRCUIT
The MC13109 integrates several of the functions required for a cordless
telephone into a single integrated circuit. This significantly reduces
component count, board space requirements, and external adjustments. It is
designed for use in both the handset and the base.
