Abstract:
1. A voltage translator connected between a first component having a first voltage supply and a second component having a second voltage supply, wherein the first voltage supply differs from the second voltage supply, the voltage translator couples to supply an operating output voltage for the second component, comprising: a first inverter coupled between the input and a first node; a second inverter coupled between the first node and an output node; a third inverter coupled between the output node and a second node; a fourth inverter coupled between the second node and a third node; a first circuit portion coupled between the fourth inverter and first inverter that establishes the low-to-high switching point; and a second circuit portion coupled between the fourth inverter and the first inverter that blocks switching current from draining the second voltage supply after the transition from low-to-high has occurred.
