ABSTRACT:
An output boundary scan cell includes an output buffer structure (51) connected between a shared capture/shift memory (17) and an output terminal. The output buffer structure is responsive to initiation of a test mode of operation for latching at the output terminal functional test data from the shared capture/shift memory and for isolating the output terminal from test data subsequently stored in the shared capture/shift memory during the test mode of operation.
