Abstract
A digital signal voltage level shifter includes an edge detector that detects assertion of a digital input signal from a first logic circuit in a source voltage domain, and an output module triggered by the edge detector for asserting a digital output signal corresponding to the digital input signal for a second logic circuit in a destination voltage domain. The edge detector and the output module are supplied with power only from a power supply of the destination voltage domain and are not connected to a power supply of the source voltage domain.
