CMOS Analog Clock IC

OVERVIEW

The CF5760 series are analog clock ICs that derive their timing from a 32.768 kHz oscillator element. They

feature a reset function (optional seconds control function) which can be used to maintain accurate time. Vari-

ous alarm functions and motor outputs are available to match a wide range of clock speciﬁcations.
