Digital IC Tester

An Integrated Circuit tester (IC tester) is used to test Integrated Circuits (ICs). We can easily test any digital IC using this kind of an IC tester. For testing an IC, we need to use different hardware circuits for different ICs; like we need a particular kind of tester for testing a logic gate and another for testing flip flops or shift registers which involves more complication and time involved will also be more. So here’s an IC tester to overcome this problem. Unlike other IC testers, this is more reliable and easier since we don’t need to rig up different kind of circuits for different kind of ICs, each time we need to test them.

Unlike the IC testers available in the market today which are usually expensive, this IC tester is affordable and user-friendly. This IC tester is constructed using 8951 microcontroller along with a keyboard and a display unit. It can test digital ICs having a maximum of 24 pins. Since it is programmable, any number of ICs can be tested within the constraint of the memory available. This IC tester can be used to test a wide variety of ICs which includes simple logic gates and also sequential and combinational ICs like flip-flops, counters, shift registers etc. It is portable and easy to use.

The block diagram of the programmable digital IC tester is as shown in below. It consists of two 8951 microcontroller ICs, a 24-pin IC socket, a keyboard unit, a display unit and indicators.

To test a particular digital IC, one needs to insert the IC into the IC socket and enter the IC number using the keyboard and then press the “ENTER” key. The IC number gets displayed in the 7-segment display unit.

Four LEDs are provided as indicators. If the IC being tested is a logic gate, then each of the 4 indicator LEDs correspond to the 4 gates of the IC. In any other case wherein the inserted IC is not a logic gate, all the 4 LEDs work as a single indicator.

  12. hello ….. i am impressed by ur project and have decided to make it myself
    but as i am a novice i have decided only to make this project 4 7400 series
    IC (I have selected 6 basics IC’s for this purpose). I am having problems
    interfacing the keypad with the microcontroller i would be very thankful
    to u if u can please email ur code for interfacing keypad.

    anticipating ur reply eagerly
    Your’s Sincerely

    plz send me the details about digital ic tester project including ckt
    diagram. I will be really thankfull to you.

  15. hi sir.
    sir i am struggling with the designing of digital ic tester. sir i am the
    student of e&tc engg. 3rd year, and as its my 1st project of micro-controller
    so plz kindly help me in designing a ic tester.
    i ll be thankfull to you.

  16. Sir,

    Good Day,

    I need your help in order for me to get the full article of this project.

    Thank you in anticipation

    Yours sincerely.

  17. I think Bigfoot is blurry, that’s the problem. It’s not the photographer’s fault. Bigfoot is blurry, and that’s extra scary to me. There’s a large, out-of-focus monster roaming the countryside. Run, he’s fuzzy, get out of here.

  18. hi, i am having problem with the project. PLs, could u send me the codes
    and and the circuit diagram.

  19. Hey, I just read this project and am amazed at how you made this remarkable IC tester.

  20. sir,i also want to do this project my self. . . .but i tried also but i not getting how to interface the IC SOCKET AND LEDS and keypads………SO sir please send me the circuit diagram and source code and more information..so please help me sir…….

  21. Yes sir.I also need your help if you don’t mind may i ask a favor from you.Could you please send me the complete source code and circuit diagram.I’m also interested to make this project in my final.Please sir.Hoping for your kind response.

  22. And i have question sir.,is the circuit diagram found above complete???And how about the program??could I use it???

  23. Dear sir,

    I wonder if it is possible to get more information about the project?(technical information)
    If it is,can you send me all the details?
