CF5760 series
CMOS Analog Clock IC
OVERVIEW
The CF5760 series are analog clock ICs that derive their timing from a 32.768 kHz oscillator element. They
feature a reset function (optional seconds control function) which can be used to maintain accurate time. Vari-
ous alarm functions and motor outputs are available to match a wide range of clock specifications.
FEATURES
I 1.2 to 2.0V operating supply voltage
I 1.2µA (typ) / 1.5V current consumption

1. RL is the load resistance connected between O1 and O2.
2. CF5760AA/ CC/ FC/ HA: If the outputs (AO or AON) are short circuit, the output current is IAO 900 µA.
3. The F output voltage rating, VF , when a load capacitance, CL, is connected between pin F and VSS, is the difference voltage between the center volt-
age, 0.5VDD, and the peak voltage.
4. CG is the capacitance between VDD and XT. CD is the capacitance between VDD and XTN.
