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. 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 connect-
ing Q4 to the enable input of the subsequent counter while
the CLOCK input of the latter is held low.
