IW4520B Dual Binary Up Counter

TECHNICAL DATA IW4520B Dual Up-Counter High-Voltage Silicon-Gate CMOS The IW4520B Dual Binary 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 hi.
