Abstract
An application specific integrated circuit, for use with a circuit having a particular electrical characteristic, e.g. ringing or impedance, has an output pad with an output transistor having a drain connected to the output pad and a gate connected to the drain of a predriver transistor. A predriver time constant is derived from the gate-source capacitance of the output transistor and resistance of the predriver transistor. The predriver time constant is above a selected threshold based on the electrical characteristic such that the predriver transistor is operable to switch the output transistor at a sufficiently slow rate to avoid ringing.
