DualBinaryUp Countereachcon-
sist 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 nega-
tive-going transition. For single-unit operation the
Enable input is maintained ”high” and the counter
advances on each positive-going transition of the
Clock. The counters are cleared by high levels on
their Reset lines. The counter can be cascaded in
the ripple mode by connecting Q4 to the enable

of the latter is held low.
