CD4006 18-Stage Static Shift Register


CD4006 belongs to the 4000 Series CMOS Logic Family of Integrated Circuits (IC’s) constructed with N- and P-channel enhancement mode transistors. CD4006 has an 18-Stage Static Shift Register.

CD4006 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.

CD4006 Features

  • Wide supply voltage range 3.0V to 15V
  • High noise immunity 0.45 VDD (typ.)
  • Low power TTL fan out of 2 driving 74L
    • compatibility or 1 driving 74LS
  • Low clock input capacitance 6 pF (typ.)
  • Medium speed 10 MHz (typ.) (with VDD = 10V
