HCC4566B
DESCRIPTION
The HCC4566B and HCF4566B are monolithic integrated circuits, available in 16-lead dual-in-line plastic or ceramic packages and plastic micro packages. 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 multivibrator 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.
