CF5761 series

CMOS Analog Clock IC with Alarm Function

OVERVIEW

The CF5761 series are analog clock ICs with alarm functions that derive their timing from a standard

32.768kHz oscillator element. Two kinds of alarm output are available and can be selected using a control pin.

The series lineup comprises devices with various alarm patterns and motor outputs for a wide range of clock

speciï¬cations. They support convenient functions, such as input chattering elimination circuit and power-on

clear functions. They are fabricated using Molybdenum-gate CMOS process, realizing low power consump-

tion.
