Patent ID: 7057438

Claim:
An output circuit for outputting, based on a first and a second drive signal and a first and a second output signal, comprising: first and second signal level converting circuits respectively converting the first and the second drive signal into a signal of a prescribed level and outputting the signal; a first differential circuit outputting a signal corresponding to a difference between the signal outputted by the first signal level converting circuit and the signal outputted by the second signal level converting circuit; a second differential circuit outputting a signal corresponding to a difference between the signal outputted by the second signal level converting circuit and the signal outputted by the first signal level converting circuit; a first signal generating circuit generating the first output signal based on the signal outputted by the first differential circuit; a second signal generating circuit generating the second output signal based on the signal outputted by the second differential circuit; a first inverting circuit inverting an input signal and outputting the first drive signal; and a second inverting circuit inverting the first drive signal and outputting the second drive signal, wherein the first and second inverting circuits operate upon receipt of a power supply from a first and a second source potential and the first and second signal level converting circuits, the first and second differential circuits, and the first and second output signal generating circuits operate upon receipt of a power supply from the first and a third source potential.
