incrementing on either the positive-going or
negative going transitions. For single-unit
operations 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 input of the subsequent counter
while the clock input of the latter is held low.
