CD4011 Quad 2-input NAND Gate


CD4011 belongs to the 4000 Series CMOS Logic Family of Integrated Circuits (IC’s) constructed with N- and P-channel enhancement mode transistors. CD4011 has Quad 2-input NAND Gate

CD4011 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.

CD4011 Features

  • Low power TTL:
    • Fan out of 2 driving 74L compatibility: or 1 driving 74LS
  • 5V–10V–15V parametric ratings
  • Symmetrical output characteristics
  • Maximum input leakage 1 µA at 15V over full temperature range
