Integrated-Circuit Tester

INTEGRATED-CIRCUIT TESTER Ili11 1 ilil 11.1191111%111111111 { 1 : ~IleillliiiitiVllliiillllti This IC tester, designed by ELV GmbH, comes as an insertion card for IBM PC-XT/AT and compatibles. The card and the associated ZIF socket allow logic function tests to be carried out on a wide range of CMOS and TTL integrated circuits housed in DIL packages with up to 20 pins. The article also describes the menu-driven control program for the IC tester, which makes use of a user-definable library to test over 500 standard components. It is often necessary to check the operation of standard ICs, whether these are new or used. Testing small-scale integration (SSI) circuits with relatively few gates can be done without too much trouble. However, as the ICs become more complex, check- ing them with the aid of simple tools such as switches and LEDs becomes much more difficult. In such cases, the IC in question must be removed from the cir- cuit for a separate test, which can be very time-consu...
