The HCC4522B and HCF4522B are monolithic in-
tegrated circuits, available in 16-lead dual-in-line
plasticorceramic packages and plastic micropack-
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 inputallowscascade 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.
