The HCC4566B and HCF4566B are monolithic in-

tegrated circuits, available in 16-lead dual-in-line

plastic or ceramic packages and plastic micro pack-

ages.

The HCC4566B and HCF4566B are industrial time

base generators. They consist of a divide-by-10

ripple counter and a divide-by-5 or divide-by-6 ripple

counter to permit stable time generation from a 50

or 60Hz line.

Cascading these devices as divide by 60 counters

provides a seconds and minutes counter with an

output in BCD format. An internal monostable multi-

vibrator is included whose output can be used as a

reset or clock pulse providing additional frequency

flexibility. A divide-by-5 facility allows the generation

of a 1Hz signal from the European 50Hz-line.
