One aspect of the invention is an integrated circuit (10,110) comprising a digital circuit operable to generate a first signal (21,111) and a driver circuit (20 and 30, 120 and 130) coupled to the signal generating circuit (21,111) and to an output load (40, 140). The driver circuit (20 and 30, 120 and 130) comprises a first transistor (MDA,MODA) operable to sink a first amount of current from an output node (38, 138) when activated and a second transistor (MDC,MODC) operable to sink a second amount of current from the output node (38, 138) when activated. The driver circuit (20 and 30, 120 and 130) also comprises a third transistor (MP1, MP4) coupled to the first transistor (MDA,MODA) and operable to activate the first transistor (MDA,MODA) and the second transistor (MDC,MODC) in response to a transition of a first signal. The driver circuit (20 and 30, 120 and 130) further comprises at least one resistive element (R3, R6) coupled to the second transistor (MDC,MODC) and to the third transistor (MP1, MP4) that is operable to delay activation of the second transistor (MDC,MODC) until after activation of the first transistor (MDA,MODA).
