Abstract: An I/O module configured to operate over a range of voltage supplies includes a transmit path circuit and a receive path circuit that are each configured to convert a data signal between a core voltage domain and one of a first voltage domain (e.g., a high voltage domain) and a second voltage domain (e.g., a low voltage domain) in response to a mode select signal.

Abstract: An assembly includes a signal input, a signal output, a pull-up stack coupled to the signal input and to the signal output, a pull-down stack coupled to the signal input and to the signal output, and a hysteresis assembly coupled to the pull-up stack and to the pull-down stack. The pull-up stack comprises a pair of metal oxide semiconductor field-effect transistors (transistors) coupled in series, each transistor of the pair of transistors comprising a gate coupled to the signal input. The pull-down stack comprises a plurality of transistors coupled in series, the plurality of transistors comprising: a first transistor comprising a gate coupled to the signal input, a second transistor comprising a gate coupled to the signal input, and a third transistor. The hysteresis assembly comprises a pair of transistors, each transistor of the pair of transistors of the hysteresis assembly having a gate coupled to the signal output.
