Abstract

An output driver includes a first pre-driver circuit, a first driver circuit, a second pre-driver circuit, a second driver circuit, and a feedback network. The first pre-driver circuit pre-drives a first data input signal to generate a first pre-driving output signal. The first driver circuit drives the first pre-driving output signal to generate a first data output signal. The second pre-driver circuit pre-drives a second data input signal to generate a second pre-driving output signal, wherein the first data input signal and the second data input signal are a differential input of the output driver. The second driver circuit drives the second pre-driving output signal to generate a second data output signal. The feedback network performs a latching operation upon the first pre-driving output signal and the second pre-driving output signal according to the first data output signal and the second data output signal.
