TECHNICAL DATA

IW4518B

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.
