BiCMOS output driver circuit.

摘要

A BiCMOS power driver circuit for interfacing to a bus comprises means for channelling current from a power source to the base of a bipolar device to pull the output all the way down to within a bipolar VSAT voltage drop of ground, and then uses feedback to turn-off the pull-down circuit to conserve power. A similar circuit functions to provide Incident Wave Switching and Glitch Suppression by monitoring the voltage level at the output and sinking current as necessary to maintain a low logic level.
