Abstract: In accordance with an embodiment, a transceiver includes a bidirectional data transmission circuit coupled to a direction control circuit and method for transmitting electrical signals in one or more directions. The direction control circuit generates a comparison signal in response to comparing input/output signals of the bidirectional data transmission circuit. Transmission path enable signals are generated in response to the comparison signal.

Abstract: A monolithically integrated multiplexer-translator-demultiplexer and a method for multiplexing and translating an electrical signal or demultiplexing and translating an electrical signal. A multiplexer and a demultiplexer are monolithically integrated with a translator. Circuits that operate at different voltage supply levels from each other may be coupled to the multiplexer and a circuit that operates at a different voltage supply level from the circuits coupled to the multiplexer or that operates at the same voltage supply level as at least one of the circuits coupled to the multiplexer is coupled to the demultiplexer. The monolithically integrated multiplexer-translator-demultiplexer selects a signal from one of the circuits coupled to the multiplexer, translates its voltage level and provides the translated signal level as an output signal.
