CMOS Analog Clock IC
OVERVIEW
The CF5746 Series devices are analog clock ICs that
derive their timing from a 32 kHz oscillator element.
They feature alarm outputs, snooze function and
alarm auto-stop function. They can be configured to
match a wide variety of clock specifications, alarm
functions and motor outputs.
