Patent Number: 6,763,487

Title: IC with latching and switched I/O buffers

Abstract: An electronic integrated circuit includes a signal path connected between the functional logic (15) thereof and an external output terminal thereof, which signal path includes a memory circuit (121C, 127C). The memory circuit is coupled to the output terminal and is selectively operable to detect and resolve voltage contention at the output terminal, and is also selectively operable to isolate itself from voltages at the output terminal.
