Abstract
The present invention relates to a bus control buffer amplifier. The output terminal is associated with a first pull-down N-channel MOS transistor and with a second pull-up N-channel MOS transistor. The first N-channel MOS transistor is directly controlled by an input signal. The second MOS transistor is an N-channel transistor, and its gate is controlled by a third pull-down N-channel MOS transistor directly controlled by the input signal, and by a fourth pull-up N-channel MOS transistor, which is controlled by the inverted input signal. The fourth N-channel MOS transistor has a very abrupt drain-substrate junction.
