ABSTRACT:
A digital driver circuit employs an output transistor having an uncommitted collector that can act as a current sink connectable to a peripheral element that is to be controlled. The base of the output transistor is coupled to a driver circuit that controls the output transistor conduction. The driver input is coupled to a pair of cascaded current mirrors which act to switch the driver off and on. An input stage is coupled to control the current mirrors in response to a low current logic signal.
