Dual Up-Counter
High-Voltage Silicon-Gate CMOS
The IW4518B Dual BCD Up-Counter consists 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.
Operating Voltage Range: 3.0 to 18 V
Maximum input current of 1
μ
A at 18 V over full package-
