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 specifications. 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 consumption.
