Claim:
1. A circuit comprising: an input; a first inverter including a first transistor pair and a second transistor pair, the first inverter being configured to invert a first signal on the input to a second signal on an intermediate input; a second inverter including a third transistor pair and a fourth transistor pair, the second inverter being configured to invert the second signal on the intermediate input to a third signal on an output; a first charge steering transistor configured to steer a first current away from the first transistor pair, the first current being generated within the first transistor pair from an ionization radiation; a second charge steering transistor configured to steer a second current away from the second transistor pair, the second current being generated within the transistor pair from the ionization radiation; a third charge steering transistor configured to steer a third current away from the transistor pair, the third current being generated within the third transistor pair from the ionization radiation; and a fourth charge steering transistor configured to steer a fourth current away from the fourth transistor pair, the fourth current being generated within the fourth transistor pair from the ionization radiation.
