CF5746 Series
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.
FEATURES
s 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)
s Alarm outputs
• Compatible with electronic sound alarms and
motor bells
• 4-step increasing volume alarm output
(CF5746AAB, ADC, AEA, AFA (AO1), AGA
(AO1))
s Snooze function
• Temporarily stops alarm output and then re-
starts after a fixed time
s Debouce circuit (AI/SNZ pin)
s Test functions
• Shortening snooze time and auto-stop time
• Increasing motor speed (excluding
CF5746BCA)
s Power-ON clear function
s 1.5 V supply voltage
s Chip form
