CD4020 DIP IC

4.00 د.إ

CD4020 is 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.

The CD4020 type is supplied in 16-lead hermetic dual-in-line ceramic packages (F3A suffix), 16-lead dual-in-line plastic packages (E suffix), 16-lead small-outline packages (NSR suffix), and 16-lead thin shrink small-outline packages (PW and PWR suffixes).

Features:-

  • 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 ?A 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”
  • Applications:
    • Control counters
    • Timers
    • Frequency dividers
    • Time-delay circuits
