Abstract
The present invention incorporates level-shifting functions within a multiplexer circuit that may be implemented in IC devices having low and high voltage domains. The multiplexer circuit utilizes pseudo-differential multiplexing architectures and employs level-shifting techniques to convert low-voltage signals received from the low-voltage domain into high-voltage signals more suitable for controlling the propagation of a selected input signal through the pass gates of the multiplexer circuit. For some embodiments, some of the select signals may be decoded to generate a number of decoded select signals that can be used to control the selective routing of signals through the multiplexer.
