MC13110A
MC13111A
Universal Cordless Telephone
Subsystem IC
The MC13110A and MC13111A integrates several of the functions
required for a cordless telephone into a single integrated circuit. This
significantly reduces component count, board space requirements, external
adjustments, and lowers overall costs. It is designed for use in both the
handset and the base.
