ACKNOWLEDGEMENT

The completion of any project brings with it a sense of satisfaction, but it is never complete without thanking those people who made it possible and whose constant support has crowned our efforts with success. We are thankful our guide, Prof. N.P. Deshpande, Head of the Department, Electronics and Telecommunication PVG’s COET, PUNE, of Electronics and Telecommunication for his expert guidance, encouragement and valuable suggestions at every step. We would like to express our gratitude to Prof. R.G. Kaduskar, for encouraging and inspiring us to carry out the project in the department lab.

We also would like to thank all the staff members and lab assistants of E&TC dept. for providing us with the all required facilities and support towards the completion of the project.

We would also like to thank our seniors who always helped us to overcome our problems during the course of the project.
We are extremely happy to acknowledge and express our sincere gratitude to our parents for their constant support and encouragement and last but not the least, friends and well wishers for their help and cooperation and solutions to problems during the course of the project.

ABSTRACT

The digital IC tester is implemented by using the 89C51 microcontroller board. The processing of the inputs and outputs is done by the microcontroller. The display part on the microcontroller board is modeled using LCD. After the successful testing of the IC, the result is displayed on the LCD.

The basic function of the digital IC tester is to test a digital IC for correct logical functioning as described in the truth table and/or function table. 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 model applies the...
