CD4518BMS
Description
CD4518BMS Dual BCD Up Counter and CD4520BMS Dual Binary Up Counter each consist of two identical, internally synchronous 4-stage counters. The counter stages are D-type flip-flops having interchangeable CLOCK and ENABLE lines for incrementing on either the positive-going or negative-going transition.
