ABSTRACT:
A universal performance board for use with integrated circuit testers operates to set the power supply attribute relays or I/O loads on a performance board or load board through an integrated circuit relay control circuit. The control information for the power supply attribute relays or I/O loads is supplied from the tester to the data input of the relay control circuit at the start-up of operation for testing each new integrated circuit under test. The required control information is loaded into the relay control circuit, which then selectively operates the power supply attribute relays or I/O loads. After the relay control information has been loaded into the control circuit, the tester channels are released to be used by the tester in a normal testing function of the integrated circuit device under test. A battery back-up support is provided for memory retention in the relay control circuit; so that the control information is retained until it is subsequently changed by the supply of new control information from the tester whenever the integrated circuit device under test is changed to a different type of device.
