CD4518 - Dual BCD Up Counter

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 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.

  • Medium-speed operation - 
       6-MHz typical clock frequency at 10 V
  • Positive- or negative-edge triggering
  • Synchronous internal carry propagation
  • 100% tested for quiescent current at 20 V
  • Maximum input current of 1 µA at 18 V over full package-temperature range; 100 nA at 18 V and 25°C
  • Noise margin (over full package-temperature range):
    • 1 V at VDD = 5 V
    • 2 V at VDD = 10 V
    • 2.5 V at VDD = 15 V
  • 5-V, 10-V, and 15-V parametric ratings
  • Standardized, symmetrical output characteristics
  • Meets all requirements of JEDEC Tentative Standard No. 13B, "Standard Specifications for Description of ’B’ Series CMOS Devices"
  • Multistage synchronous counting
  • Multistage ripple counting
  • Frequency dividers
