Method and apparatus for properly disabling high current parts in a parallel test environment

A parallel test system and method for testing integrated circuit devices which can reliably prevent devices that should not be active due to a blown fuse from generating random data signals which can adversely impact the test results of other chips being tested are disclosed. The state of each fuse that protects a respective socket on a test board is determined by a controller, such as an Application Specific Integrated Circuit (ASIC), built onto the test board. When it is determined that a specific fuse is open, i.e., the fuse has blown due to a high current condition, the device inserted into the socket protected by the fuse will have its I/O lines disabled by the controller, thereby effectively shutting off the device completely and preventing it from generating and transmitting random data to the test device.
