ABSTRACT:
A circuit device for variously controlling a current drive capacity of a semiconductor IC device as required by the user. A circuit device, capable of preventing a semiconductor IC device from failing to drive an external device, preventing an operational speed of the semiconductor IC device from being reduced, and preventing noise from being transferred to the external device.
