Patent ID: 7723794

Claim:
A load driving device comprising: a drive control signal generation circuit generating a load drive control signal; and a semiconductor buffer circuit generating an output signal in response to said load drive control signal, wherein said semiconductor buffer circuit includes a pair of gate driven switching elements which are connected to each other in a push-pull configuration and driven by said load drive control signal, an output terminal which is connected to a connection point between one controlled electrode of one of said pair of gate driven switching elements and one controlled electrode of an other of said pair of gate driven switching elements, and a power source terminal and a ground connection terminal respectively connected to an other controlled electrode of said one of said pair of gate driven switching elements and an other controlled electrode of the other of said pair of gate driven switching elements, wherein the other of the pair of gate driven switching elements includes a set of MOS transistors which are connected in parallel to each other and between said connection point and said ground connection terminal, and whose gates are driven by said load drive control signal.
