CF5760DA

CF5760 series NIPPON PRECISION CIRCUITS INC. CMOS Analog Clock IC 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.
