CF5760 series

CMOS Analog Clock IC

NIPPON PRECISION CIRCUITS INC.

OVERVIEW

The CF5760 series devices 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.

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