The CD451 Up counter consists of two identical synchronous 4-stage counters. The image below shows the logic circuit of the BCD Up counter.

The counter stages are the D-type flip-flops having interchangeable CLOCK and ENABLE lines for incrementing the positive or negative-going transition, For the operation of a single unit, the ENABLE input is kept HIGH and the counter advances each positive-going transition of the CLOCK. The RESET lines clear out the HIGH levels.
