Abstract
A circuit comprises a first level shifting circuit. The level shifting circuit comprises a first and second latching differential pairs. The first latching differential pair has first and second inputs for receiving first and second input signals, first and second outputs, and first and second power supply voltage terminals for receiving a first power supply voltage. The second latching differential pair has first and second inputs coupled to the first and second outputs of the first latching differential pair, an output, and first and second power supply voltage terminals for receiving a second power supply voltage, the second power supply voltage being different from the first power supply voltage. In one embodiment, the level shifting circuit protects transistor gates of the circuit from an overvoltage.
