CD4013 Dual D Flip-Flop with Set/Reset


CD4013 belongs to the 4000 Series CMOS Logic Family of Integrated Circuits (IC’s) constructed with N- and P-channel enhancement mode transistors. CD4013 has Dual D Flip-Flop with Set/Reset

CD4013 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.

CD4013 Features

  • Static Flip-Flop Operation – Retains State Indefinitely With Clock Level Either “High” Or “Low”
  • Medium-Speed Operation – 16 MHz (typ.) Clock Toggle Rate at 10V
  • Standardized Symmetrical Output Characteristics
  • 100% Tested for Quiescent Current at 20V
  • Maximum Input Current of 1µA at 18V Over Full Package Temperature Range; 100nA at 18V and +25oC
  • Noise Margin (Over Full Package Temperature Range):
    • 1V at VDD = 5V
    • 2V at VDD = 10V
    • 2.5V at VDD = 15V
  • 5V, 10V and 15V Parametric Ratings
