NIPPON PRECISION CIRCUITS INC.—1
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.
