This family of monolithic integrated circuits has
been specially designed for use as frequency
dividers in Quartz Crystal controlled wrist
watches and clocks. The devices consist of an
oscillator, frequency divider chain, pulse
shaper and output stage. An external resistor is
used for current consumption programming.
The output stages have been designed to suit
the majority· of available movements. 'These
devices are available in several different circuit
variations. Please contact factory for special
requirements.
