Input/output buffer with overcurrent protection circuit |
摘要 |
An overcurrent protection circuit for input/Output (I/O) buffers for a Field Programmable Gate Array wherein short circuits can be detected and the output current limited so as to avoid damaging the device. I/O buffers having the overcurrent protection circuit can detect a contention between the buffers. In order to eliminate the contention, certain I/O buffers will go into a noncontending state.
