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.

CF5760 series
Reset Function (optional seconds control function)
When AI/R goes active level for a reset, the motor output stops. When the reset is released, the first motor out-
put pulse occurs on the output pin opposite to that which had the last output pulse immediately before the reset.

F Output Function
The AON pin may be replaced by the F pin which is used to output a 32kHz signal (unaffected by the reset
function).
