List of 4000 Series IC

The 4000-series Integrated Circuits (IC) is a classic series of CMOS chips. It has a bunch of useful basic features such as logic gates, 7-segment decoders, counters, and more.

Below you’ll find a non-exhaustive list of the most common 4000-series chips. Click on the IC number of a chip to learn more about its pins, functions and example circuits.

More ICs will be added. If you have a request, let me know in the comments!

IC #	Pinout	Description
4001		Quad 2-input NOR gate: An IC with four standard NOR gates.
4008		4-bit Binary Full Adder: An IC for adding two 4-bit binary numbers.
4011		Quad 2-input NAND gate: An IC with four standard NAND gates.
4013		Dual D-type flip-flop: An IC with two D Flip-Flops.
4017		5-stage Johnson Decade Counter: A decade counter with ten outputs. Each output represents a number, 0 to 9, and goes HIGH when the counter reaches it.
4060		14-stage ripple-carry binary counter/divider and oscillator: A binary counter with oscillator integrated. Add two resistors and a capacitor to create various time delays or frequencies.
4071		Quad 2-input OR gate: An IC with four standard OR gates.
4081		Quad 2-input AND gate: An IC with four standard AND gates.
4511		BCD to 7-segment latch/decoder/driver: A BCD to 7-segment decoder. This IC converts binary-coded decimals to a seven-segment display.

Thanks to Inductiveload who made the pinout drawings that I used as the starting point for the pinouts on this page. Check out the 4000 Series Overview on Wikimedia for their original work.

Good to know about the 4000 series:

• Many different manufacturers have made these throughout the time, so you’ll usually find the chip number with a prefix such as CD4xxx, HEF4xxx, or NTE4xxx.
• All unused inputs (even from unused gates) should always be connected to either GND or VCC to avoid unnecessary current consumption.
• Most chips support a voltage supply of between 3V and 15V. Some versions support up to 20V.
