Abstract
An integrated circuit device includes a differential amplifier, an output driver and a control circuit. The differential amplifier is responsive to a pair of differential input signals and may include a pull-down current source responsive to a pair of bias signals. The output driver has a pull-up path and pull-down path therein. These paths are joined together at an output node. The output driver has a first input terminal electrically coupled to a first output terminal of the differential amplifier. The control circuit is electrically coupled to the differential amplifier and a second input terminal of the output driver. The control circuit is configured to dispose the pull-down path in a nonconductive state when the output node is being switched low-to-high.
