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 connecting Q4 to the enable input of the subsequent counter while
the CLOCK input of the latter is held low.
The CD4518BMS and CD4520BMS are supplied in these
16-lead outline packages:
