Abstract
This current switch driving circuitry, particularly for, but not necessarily limited to, inductive device current switching, comprises a pair of output transistors constituting a driving transistor for turning ON a subsequent switching transistor and a current sinking transistor for turning OFF that switching transistor with circuit provisions for maintaining the two transistors in a low power consuming standby state. A pair of receiver circuits are arranged for applying ON and OFF logical signals individually to the two transistors by way of intermediate circuitry having current multiplying circuitry for deriving the necessary driving power with a minimum of power consumed.
