CD4518 Dual BCD Up-Counter and CD4520 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 • Medium-speed operation -    6-MHz typical clock frequency at 10 V\n• Synchronous internal carry propagation\n• Maximum input current of 1 µA at 18 V over full package-temperature range; 100 nA at 18 V and 25°C\n• 1 V at VDD = 5 V\n• 2.5 V at VDD = 15 V\n• 5-V, 10-V, and 15-V parametric ratings\n• ;
