CF5760 series
CMOS Analog Clock IC
| The CF5760 series are analog clock ICs that derive their timing from a 32.768kHz 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. |
