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. These are great building blocks for digital electronics. This series is an alternative to the 7400 series which has a lot of the same functionality.

Below you’ll find a list of the most common 4000-series chips.

4013		Dual D-type flip-flop: An IC with two D Flip-Flops.
4014		8-stage parallel-in shift register: An 8-bit shift-register with parallel inputs. Great for creating a parallel-to-serial converter.
4015		Dual 4-bit static shift register: This chip contains two 4-bit shift registers with serial input and parallel output pins. Great for adding more output pins to a microcontroller or Arduino.
4016		Quad bilateral switch: An IC with four bidirectional, analog switches which can be controlled individually using a control pin. The signal can flow in either direction between the two pins of each switch.
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.

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 might consume current (even for unused gates), so connect them all to either GND or VCC if you want to avoid unnecessary current consumption.
• Most chips support a voltage supply of between 3V and 15V. Some versions support up to 20V.
