ABSTRACT:
A serial interface apparatus comprises a driver for generating a differential communication signal and a pre-driver for driving the driver circuit. The pre-driver receives an input signal that alternates between VDD and ground and produces an output signal that alternates between a lower limit that is greater than ground and an upper limit that is less than VDD. The pre-driver comprises input circuitry and actuation circuitry, and the actuation circuitry comprises transistors of a single channel type.
