摘要：
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 is operable to resolve voltage contention at the output terminal.
