摘要:
A configuration for identifying contact faults during the testing of integrated circuits with a multiplicity of pins which protrude from a housing and are connected to respective pads on a semiconductor body of the integrated circuit. Pull-up or pull-down devices are connected between respective pads and input buffers and in each case hold the pads at a high or low potential by impressing a holding current, if contact has not been made with a pin associated with the pad during testing, the result being that activation of the circuit section connected to the pin is avoided.
