Abstract:
A method of operating a pad driver, the method comprising the steps of:generating an input signal; generating a first voltage from a first pre-driver, the first pre-driver including a first path, comprising an inverting level shifter and a tri-state inverter, the first path operating during high voltage operations and a second path comprising a tri-state buffer, the second path operating during low voltage operations, the first pre-driver generating the first voltage in response to the input signal, the first voltage driving a first device and causing the first device to operate producing a first signal; generating a second voltage from a second pre-driver in response to the input signal, the second voltage driving a second device and causing the second device to operate producing a second signal; and generating an output voltage in response to the first signal and in response to the second signal.
