CD4020BE DIP-16 DataSheet

CMOS 14-Stage Ripple-Carry Binary Counter/Divider

CD4020B, CD4024B, and CD4040B are ripple-carry binary counters. All counter stages are master-slave flip-flops. The state of a counter advances one count on the negative transition of each input pulse; a high level on the RESET line resets the counter to its all zeros state. Schmitt trigger action on the input-pulse line permits unlimited rise and fall times. All inputs and outputs are buffered


  • Medium-speed operation
  • Fully static operation
  • Buffered inputs and outputs
  • 100% tested for quiescent current at 20 V
  • Standardized, symmetrical output characteristics
  • Fully static operation
  • Common reset
  • 5-V, 10-V, and 15-V parametric ratings
  • 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
  • Meets all requirements of JEDEC Tentative Standard No. 13B, "Standard Specifications for Description of 'B' Series CMOS Devices"
    • Control counters
    • Timers
    • Frequency dividers
    • Time-delay circuits
