Abstract
A driver circuit has a single feedback transistor in the driver transistor well to provide a momentary feedback from source to gate and maintain conductance of the driver transistor during turnoff of the driver transistor and thus reduce ringing oscillation at the transistor source output. An enable/disable signal is applied to control conduction circuitry and the driver transistor and force the output to a high impedance state when the circuit is disabled. Clocked operation of the driver circuit is provided with circuitry merged with a latch. A terminal for receiving a global i.sub.dd test signal controls circuitry removing power to the driver circuit and applying a ground potential to the driver output in response to the global i.sub.dd test signal.
