IW4518B Dual BCD Up Counter

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 th.
