CD4024 7-stage Binary Counter


CD4024 belongs to the 4000 Series CMOS Logic Family of Integrated Circuits (IC’s) constructed with N- and P-channel enhancement mode transistors. CD4024 has 7-stage Binary Counter

CD4024 has a supply voltage range of 5V to 20V, which is much higher than any contemporary logic family. It has buffered output which improves transfer characteristics by providing very high gain. All inputs are protected against static discharge with diodes to VDD and VSS.

CD4024 Features

  • Wide supply voltage range: 3.0V to 15V
  • High noise immunity: 0.45 VDD (Typ.)
  • Low power TTL compatibility: Fan out of 2 driving 74L or 1 driving 74LS
  • High speed: 12 MHz (Typ.)
    • input pulse rate VDD − VSS = 10V
  • Fully static operation
