CMOS IC

LC73815M

FSK 1200 Baud Modem and DTMF Receiver

• Digital guard timer circuits for the DTMF signal

detection signal pins

• Operating voltage range: 4.5 to 5.5 V

• Low-power mode that can contribute to energy savings

• 36-pin package (MFP-36S)

Overview

The LC73815M is a telephone IC that integrates on a

single chip both an FSK modem, which receives pre-call

reporting services such as caller ID and performs other

data send/receive functions, and a DTMF receiver circuit

that can handle remote control functions for telephone

answering machine applications.
