The HCC4522B and HCF4522B are monolithic in- tegrated circuits, available in 16-lead dual-in-line plastic or ceramic packages and plastic micro pack-ages.

The HCC4522B and HCF4522B are programm-able, BCD down counters with a decoded "0" state output for divide-by-N applications. The counters are cascadable. In single stage applications the "0" output is applied to the Preset Enable input. The cascade feedback input allows cascade divide-by-N operation with no additional gates required. The clock Inhibit input allows disabling of the pulse counting function. Applications for these programmable divide-by-N counters include frequency synthesizers, phase-locked loops and other frequency dividing circuits where low power and/or high noise immunity is re-quired.
