DESCRIPTION
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.
