IC Chip Identification

IC Standing on its Pins

"IC" stands for "integrated circuits," which are essentially just computer chips. ICs exist everywhere and are used in a number of applications, including digital signal processing, timing, and signal amplification. Once identified, you will know what applications the IC is designed for.

  1. Identify the Serial Number

    • Find the serial number on the IC. It should be located on the top side of the chip, when the IC is standing on its metal pins. An example of a serial number would be: "74HC04." You may need to use a magnified glass in order to read the serial number.

    Find the Data Sheet

    • Look up the serial number for the IC on the Google or Yahoo! search engine. There you should find a PDF document for download from the manufacturers website. Download the data sheet.

    Information on the Data Sheet

    • Once identified you will be able to identify what each pin of the IC does, how it responds to different voltage levels, and how fast the IC able to respond to changing voltage levels.
