Abstract
Level shifting circuitry comprises a first level shifter and a second level shifter. In response to a falling edge transition of an input signal, the first level shifter generates a primary transition of a first intermediate signal faster than the second level shifter generates a secondary transition of a second intermediate signal. In response to a rising edge of the input signal, the second level shifter generates a primary transition of the second intermediate signal faster than the first level shifter generates a secondary transition of the first intermediate signal. Output switching circuitry is provided to switch an output signal between an output high voltage level and an output low voltage level in response to the primary transition of the first intermediate signal and the primary transition of the second intermediate signal.
