ABSTRACT:
An output driver circuit that compensates for variations in supply voltage to provide more consistent switching speed characteristics. In one embodiment, the output driver circuit includes a plurality of pull down devices which are connected in parallel with one another between an output node of the circuit and ground. One of the pull down devices is coupled to a source of a pull down signal to be turned on in response to the pull down signal. The other pull down devices are turned on selectively, depending upon the level of the supply voltage. The lower the supply voltage, the more pull down devices that are turned on. A latch is provided at the input of each of the pull down devices. The result of the selective enabling of the pull down devices is that a more uniform pull down speed is provided for different levels of the supply voltage.
