Description

Atmel’s low-voltage telephone circuit U3761MB-T performs all the speech and line

interface functions required in an electronic telephone set, a tone ringer, a pulse and

DTMF dialing with redial, notice function, and 13 memories. Operation below 15 mA is

possible with reduced performance.
