Logic - Counters, Dividers

Category Introduction

Counter and divider ICs are digital logic devices which tally the number of logic transitions that occur at their inputs, and resent the accumulated count using multiple parallel outputs and/or generate a single output signal transition in response to the application of some integer number of input signal transitions. In addition to simple event counting, they find use in a variety of frequency synthesis applications.
