    The document describes a digital IC tester that uses a microcontroller to test analog ICs. It sends input patterns to the IC based on its truth table and compares the outputs to stored results, declaring the IC "GOOD" if all patterns match or "NOT WORKING" if any don't along with activating an alarm. The IC name can be selected via a keypad and results are displayed on an LCD screen. It is meant to be faster and avoid errors compared to manual testing, and can be used in electronics labs and R&D centers.

    DIGITAL IC TESTER

    The Objective of this project is to test the working status of an analog IC.
    Both manual as well as microcontroller based IC testers are available in the
    market. Manual IC testing involves a lot of tiresome procedure and is prone to
    errors, apart from being a time-consuming process. On the other hand,
    microcontroller based IC testers are to handle and the chances of errors are
    negligible.

    The basic principle of testing any IC or device is to compare the outputs


    obtained from the IC under test on giving a set of input signals based on its truth
    table, with the standard results stored in the memory, for a particular set of input
    signals. If all sets of results, so obtained for a specific IC, tally with the stored
    results, the IC is declared ‘GOOD’ otherwise it is shown as ‘BAD’ and gives
    alarm.

    In this project some of the analog IC format is programmed in the


    microcontroller. When you insert the IC in Ziff socket, the microcontroller sends
    IC testing pattern to Ziff socket. If the output is correct for the given input, the IC
    working status is good LCD will display the GOOD IC. Any one input pattern is
    not matching with the IC, which is inserting in the Ziff socket; the microcontroller
    will display the “NOT WORKING” in the LCD and also activate alarm circuit for
    audible indication through the driver circuit. We have key pad for select the IC
    name, which we are going to test.
