MC13111A数据手册恩XP中文资料规格书

描述 Description

Overview The MC13110A/B and MC13111A/B 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.
