CMOS LSI
No. 5561
LC73701M
Serial Interface Dialler
Overview
The LC73701M is a DTMP/pulse output dual-system dialer CMOS LSI for use in push-button telephones. It provides an on-chip serial interface and operates under the control of data sent over that serial interface. The LC73701M can be easily controlled by the system CPU using this dedicated interface.
- The dial pulse make ratio can be specified to be either 33 or 39%.
- Wide operating voltage range Pulse mode: VDD = 1.5 to 5.5 V DTMF mode: VDD = 2.0 to 5.5 V
Package Dimensions unit: mm 3095-MFP18
