DESCRI PTION

The HCC4522B and HCF4522B are monolithic in­tegrated circuits, available in 16-lead dual-in-line
plasticor ceramicpackagesand plasticmicropack­ages.

The HCC4522B and HCF4522B are programm­able,BCD down counters with a decoded ”0” state
output for divide-by-N applications. The counters
arecascadable. In single stage applications the ”0”
output is applied to the Preset Enable input. The
cascadefeedback input allowscascade 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, phase­locked loops and other frequency dividing circuits
where low power and/or high noise immunity is re­quired.
