Abstract
A circuit integrated into a substrate and having improved noise immunity comprises logic gates for receiving and switching current from a first bus to produce a logic signal; a resistor for receiving and passing a small bias current from a second bus indicating the state of the logic signal; a transistor for receiving and passing a large drive current from a third bus in response to bias current; and the first bus has a relatively large parasitic coupling serially through the logic gates, substrate, and resistors to the second bus; while the first bus has a relatively small parasitic coupling serially through the logic gates, substrate, and transistor to the third bus.
