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!
|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.|
|4510||Up/Down BCD Counter With Preset Function: This is a BCD counter that can count up or down between 0 and 9.|
|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.|
Good to know about the 4000 series:
- The output pins usually only support a few milliamps of sink or source current.
- Lots of manufacturers have made these throughout 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.
