ABSTRACT:
Briefly, in accordance with one embodiment of the invention, an integrated circuit includes: an output buffer. The output buffer includes semiconductor devices coupled to provide circuit configurations. The output buffer is adapted to couple to separate voltage supply voltage level ports and is further adapted to switch between the circuit configurations. The respective circuit configurations are respectively specifically adapted for interoperating with other integrated circuit chips, the respective threshold voltage levels of the semiconductor devices of different other integrated circuit chips being different.
