Abstract:
1. An output circuit for output of a bi-level voltage signal taking on a first potential level and a second potential level in response to an input signal that likewise takes on the first potential level and the second potential level, comprising: a first transistor of a first conductive type having a source electrode receiving the first potential level and having a first gate electrode; a second transistor of a second conductive type having a source electrode receiving the second potential level and having a second gate electrode; and means for applying to the first gate electrode a first control signal that swings between the first potential level and a third potential level intermediate between the first potential level and the second potential level, and applying to the second gate electrode a second control signal that swings between the third potential level and the second potential level; the first transistor and the second transistor also having interconnected drain electrodes for output of the bi-level voltage signal.
