DIGITAL IC TESTER

Aim:

To design a system for testing digital IC.

 

Working Principle:

In this project we are designing a system for testing digital IC’s(74XX series). The main purpose of developing the digital IC tester is to check digital IC’s for any malfunctions before being used in any KITs/ Projects. Many times lots of time goes to waste because of malfunctioning digital IC’s, it is always better to test the IC’s before using them in any projects.
