List of 7400 Series IC

The 7400-series Integrated Circuits (IC) is a classic series of 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 4000 series which has a lot of the same functionality.

Below you’ll find a non-exhaustive list of the most common 7400-series chips.

Good to know about the 7400 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 often find the chip number with a prefix such as SN74xxx, MM74xxx, or DM74xxx.
  • There is also a military-grade version that uses 54xxx instead of 74xxx.
  • Most chips support a voltage supply of 5V.

  1. You should add a page for a XNOR gate with standard/gates to complement the 74266 with open collector gates , you’ve done that for some of the other logic gates you’ve taught us about on the page.
