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.

sir ur projects are really of great help to student community
sir This project is very usefull to me.I want hex code for ur program.
sir,we would like to do digital ic tester as our mini project..but when both the programs are build using keil(simulation software) a lot of errors are seen and was unable to create the hex file.could you please correct the same and mail me.
sir i am chethan studying in final year diploma we are doing the project that you have submitted on this website but we are not sure that it will work for every ic’s so can you tell me if it suit for all the ic’s & tell me the total cost required for this project………. please……..
Hi,
@keerthik
Pls let me know where exactly u r getting errors.
@chethan
I have written code to test only few gate Ic’s AND, OR, NOT, NAND
You can write code to test any Digital Ic’s.
sir ur projects are really of great help to student and very usefull to me.I want hex code for ur program.
this site is very helpful to me to undestand how to use 8051 mc.
this is my mini project so I like this guidance.
please help me for how to use MC with LCD and latches.
thanking you.
hi sir,
i want to do same project but using pic 18f452 and i want to make use of memory card too .
basically i want to use memory card to store tests for all kinds of ICs.and while testing when we hit the number of ic using keypad. i want pic to search for that program in the memory card. if memory card had that program then it should send it to pic and pic will perform function to test ic. and then pic shall b able to display result on LCD.
could you tell me is that possible. i will be thankful to you if you can help me with this
Sir, i m doing this project as my mini project in 3rd year engineering. I wanted to ask u, is the circuit diagram u have provided full-proof or some other components need to be connected? If yes, kindly tell the connections. Plz reply as soon as possible. Thanks!!
Sir, also tell the modifications in the codes of master IC and slave IC while using Keil software.
I am a student of Electrical Engineering at Hawassa University in Ethiopia. I have studied and chosen this project as my final year project, I am keenly interested in it. sir I am stuck with the circuit diagram. What I need is the following:
1)Complete description on how we can interface keyboard and indicator to the 8951 microcontroller
2) Is this keyboard different from the keyboard of computer, if yes How can I design it?
3)You have said that this digital IC tester is used to test any ICs and 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.Here, what part of the IC is tested? please, verify it for me.
4)Regarding to the above comments I wrote I need your response as early as possible (to mean your reply for what I have asked must be in a short period of time).
You can send me all the necessary information via my e-mail
my e-mail is:bayisahawa@yahoo.com
Thank you!
sir i hve chosen this as mah final year project but iam gettin a lot of errors in coding…please can u send me d correct code as soon as possible…………..i’ll be really thankful……
my id is pinkuvora@indiatimes.com
sir,
plz send me the programe and circuit diagram of this circuit.
Sir
I have interested to purchase this ic tester if any source to get this IC TESTER Plz inforn me and what is the actual price.
Thanking You.
Your Regars

good evening sir,
iam stutying in (b,sc) agri, 1st year iam want to the assignment -DIGITAL -IC soonly i want sir thankyou iam wait for your information..
dear sir! we r doing this project for our final year project and i just want to make sure if we cn use a constant voltage of 5 volts
pls sir i want to learn more about the 8051 keyboard interface
Dear Sir, I want to purchase digital IC Trainer. What is the price pl let me know. Thanks & Regards,
Debasish
hi sir. im interested in your project so i will make it for my final project. can you send me more details of your project.
A good idea. I wonder if external logic could be minimized with additional logic in software.
sir,,
please publish any information about “Zif socket”
………..
sir plz send me your circuit diagrams and hex code iam the student of diploma
i had taken soft copy of this project and now i will do implement this project and after i will send pure reply to u this reply may be good or may……………..
Sir
Can I use 8051 instead of 8951 in this ckt? What changes will be required? Also if possible please send the complete code to my mail.
sir can u just send me the asm code nd circuit daigram of the digital ic tester.waiying 4 ur reply…………………..

Please sir, can you kindly help me with the comprehensive assembly code for testing the logic Gates; NAND, AND, OR, NOR, and key-board interface with visual display for 8951 IC.
Hello. this is very interesting and clearly presented by you sir. Can u please mail the hex code to me.
thank you.
sir,
can u send me the circuit and programme code of the project digital ic tester…thanku sir…
Thanks for posting this! It gave me a clue how to parallel interface microcontrollers. I currently working on the same project but with a PIC micro.
Funny how most of the “graduating” students above dont even have a clue and are basically wanting to be spoon fed the answer.
Do some research and testing boys, that’s what engineers do.
Sorry for the rant.
Again, thanks for the valuable info, Sir!
please send me all details of this project
i want ko make this as my final year project
Interesting, I designed a fixture almost exactly like this in 1982 for a senior project.
Hi sir,
This is lavanya,i want assembly program for keypad and lcd interfacing to 89c51 microcontroller.if i press two keys at a time from keypad tha sting will be displayed in lcd.
