Abstract
A slew rate limited output driver circuit has an output terminal which varies between two power supply voltage levels in response to an input data signal. The output signal is slew rate limited by a capacitor. In order to prevent a full range of the output voltage from being placed across the capacitor, the voltage across the capacitor is limited to only one-half the full range by forcing one electrode of the capacitor to remain at a voltage potential equal to a reference voltage which, in one form, is substantially halfway between the two power supply voltages.
