Digital IC Tester
Thursday, November 20th, 2008An 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 can u plz send me the components list for dis project..i want to do this project..plz send the components required..im 3rd yr student
my email id is preetipednekar29@gmail.com
sir i am a engineering student in final year and i need a minor project for my academic. i am very interested in this project . can u plz mail me pcb design and a fresh copy of circuit diagram with all the required codes.
sir i’m interested in doing this project can you please send the components list,circuit diagram with the required codes and also the pcb design as soon as possible please ..
That’s not me a driven businessman, but a driven artist. I never take into consideration money. Beautiful things make money.
sir,, ur project is xlent.. i hav a small doubt sir, is there any posibility to add a new feature to display pin configuration automatically when pin inserted sir.
i’m a diploma student and i m interested in doing this project as my final year project.to continue with this project i need ASM file, HEX file of this project, circuit diagrams and i want to get the pcb layout of digital ic tester so,plz sir send the above details as soon as possible.
sir,
i am also a student and studying in final year of diploma in electronics engg. Sir i want a brief information about microconroller . and diff b/w the micocontroller and microprocessor .
as i know virtually all about the mp. but no knowledge about m controller, please help me sir..
sir can you plz tell me how to make an ic tester on a breadboard by using simple LEDs and resistors
sir i’m willing 2 work on dis project. bt execution of the program’s giving many errors. can u mail me d code??
sir,
plz mail me d latest circuit, pcb layout & program.. its urgent. plzzz
sir,i want to add a new feature to display pin number automatically when IC inserted in socket. There is any change in circuit diagram and code then plz sir send me that new circuit diagram and code….plzzz
send on my Id shahfahad_3@yahoo.com all details about the prject
Sir..i hd select ths as my 3rd yr mini projct.plz snd me layouts ,total cost,mainly hex code of d projct.
plzz send d ckt dia n detail specification of dis project..on ma mail id fast
i m intersted to do this as a major project so will u kindly provide me te source code 4 the same………..
n d detail circuit diagram……..
pls help me send the source code and ic testre c program
sir plz send me the source code.i really need it.
Thanks alot
hi
is any one have the source code of digital ic tester project ????
please if u r willing send us Proteus7 professional based design which includes LCD to show what gate is tested and other required components to complete the design.
especially AND NAND OR gate tester design.
Sir, i m doing this project as my mini project in 3rd year engineering. I want details about selection of microcontroller and its programming code language in detail. Plz help me in coding of project as soon as u possible
my email id is nayana.gaikwad@gmail.com
sir ur project is very good .U send me all the detail operation & code on my email ID pls Sir send me urgent…thank u sir
sir,good afternoon.i am a third year engg student wish to do the “digital IC tester” project.from the net i had come to know that u have also done the same project.so i want ur help in this project.
i want to know:
1:detailed circuit diagram and details abt the project.
2:how it tests the IC that is how it checks the IC.what is the logic and which parameter you have checked?
3:why to use 2 microcontrollers?
sir i wll be thankful to u,if u please help me in this matter.
u can send me the related info via the same email(please send as early as possible.

AM waiting your answer anxiously!!!
again I want to say THANK YOU SIR!!!
sir, happy holi
i am a final year student want to work on the project.
i had some problem like why 24 pin socket is place because all the gate ic of 4000& 7400 series is of 14 pin.
how the serial communication is going on between to controllers.

other than gate how many ic this controller can test.
i m 3rd year engineering student. i want to this project layout. plz send me this project layout… its urgent.
please sir,am working on my project. I need you to assist me with diagrams both schematic and block diagram and some write up to aid me in my project work.
please sir, am working on my project. I need you to assist me with schematic and block diagram of logic gate tester and some write up to aid me in my project.
sir,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 have almost completed my Digital IC tester using PIC and it works on software PROTEUS now i m at the stage of PCB layout……Problem is that the PIC18F452 has two VSS and VDD so both should be connected or any one of them????Plz Plz reply fast
Thanks…
Nayana, yes u have to connect all Vdd and Vss pins to appropriate sources…and use decoupling caps…this forum link has great info
