Abstract: The Integrated Circuit Tester is capable of testing both digital and analog ICs having 14 pin(74 series) and 8 pin(IC 555,LM741) respectively. It has flexibility in programming any number of ICs and can be tested with the memory constraints. The required input signal is applied to the IC for checking the condition of the IC and displays the output in the16x2 Liquid Crystal Display by displaying “GOOD” or “BAD” along with the IC number. The heart of the IC tester is PIC 16F877A Microcontroller which is programmed for deciding which IC , provide input , check the output and display the condition as mentioned .For digital ICs the possible input combinations are 00,01,10 and 11 and for analog IC input is given at VCC by checking the output and ground pins.

Keywords: PICmicrocontroller(16F877A), Embedded systems, IC Tester.
