ABSTRACT:
A BiCMOS logic circuit having greater drive and speed at low voltage is provided. The logic circuit includes a switching device which allows the pull-down device of the logic circuit to be driven directly by an input signal without first having to switch a MOS device. The switching device conducts current between the input terminal of the logic device and the pull-down device when the output signal equals a certain value.
