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
■ Debouce circuit (AI/SNZ pin)
■ Test functions
• Shortening snooze time and auto-stop time
• Increasing motor speed (excluding CF5746BCA)
■ Power-ON clear function
■ 1.5 V supply voltage
■ Chip form
