CF5746ABA Datasheet PDF - Nippon Precision Circuits

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.

FEATURES
■ 32.768 kHz oscillator circuit
    • Rf and Rd built-in
    • Oscillator capacitance built-in
        - CD = 30 pF (typ, excluding CF5746ADC)
        - CD = 20 pF (typ, CF5746ADC)
■ Alarm outputs
    • Compatible with electronic sound alarms and motor bells
    • 4-step increasing volume alarm output (CF5746AAB, ADC, AEA, AFA (AO1), AGA (AO1))
■ Snooze function
    • Temporarily stops alarm output and then restarts after a fixed time
