  • Integrated circuit test system
    Patent number: 5146161
    Abstract: A programmable clamping circuit is operated under the control of a tester comparator/driver circuit used to test the bi-directional input/output pins of an integrated circuit. The clamping circuit is operated during the floating or tri-state mode of operation of the pin undergoing test to clamp the potential on the input/output pin to a pre-determined voltage during any floating or tri-state mode in the test signal pattern. Control of the clamping circuit is effected in synchronism with the operation of the tester comparator/driver circuit.
