An improved logic circuit is disclosed, having an improved disable circuit for disabling the logic circuit at a substantially reduced current level. A modified form of the disable circuit enables the logic circuit to operate either in a three-state mode or in an open-collector mode, as desired. A dynamic Miller shunt is also disclosed for rapidly forcing the active drive device into the non-conducting state each time the phase splitter device assumes the non-conducting state. In addition, an active Miller shunt is disclosed for maintaining the active drive device in the non-conducting state whenever the logic circuit is disabled.
