Quad NAND (2 input) CD4011

The Quad NAND (2 input) CD4011 is a CMOS logic IC with four independent 2-input NAND gates in one 14-pin package. NAND is a universal gate, so the CD4011 can also be wired as NOT, AND and OR gates, latches and simple oscillators. Its wide supply range and low current draw make it a classic choice for battery projects, school labs and hobby circuits.

Quad NAND (2 input) CD4011 Specifications

• Function: 4 × 2-input NAND gates
• Logic family: CMOS 4000B series (CD4011B)
• Supply voltage: 3 V to 18 V
• Pins: 14 (VDD on pin 14, VSS on pin 7)
• Outputs: buffered
• Power: very low quiescent current when not switching

Quad NAND (2 input) CD4011 Applications

• Learning Boolean logic and checking truth tables
• Making NOT, AND and OR functions from NAND gates
• SR latches and switch debouncing
• RC oscillators, LED flashers, buzzers and touch switches
• Simple alarm and control circuits

What's in the Box

• 1 × CD4011 quad 2-input NAND gate IC

Tip: Tie every unused input to VDD or VSS, because floating CMOS inputs cause random switching and extra current draw. Add a 100 nF capacitor between pins 14 and 7 close to the chip, and handle it with antistatic care.
