CD4520 IC Dual Binary Up-Counter DIP-16 CD4520

Product Overview

The CD4520B is a CMOS dual binary up-counter consisting of two identical, internally synchronous 4-stage counters. Each counter stage utilizes D-type flip-flops with interchangeable CLOCK and ENABLE lines, allowing the counter to increment on either a positive-going or negative-going transition. The counters are cleared by high levels on their respective RESET lines.
