ABSTRACT:
A transistor circuitry keeps its constituent transistors from being forward biased to prevent injection of large currents into the transistor substrates, and like problems. The transistor circuitry achieves this result with a control circuit which generates a substrate control voltage and switching transistors which are prevented from receiving a high constant current voltage from an input terminal until the substrate control voltage is raised up to and held at a desired voltage level.
