摘要：
A data driver includes a first latch (322), an extension logic circuit (324), and a second latch (330). The first latch (322) has an input for receiving an input data signal, a clock input for receiving a first clock signal, and an output. The extension logic circuit (324) has an input coupled to the output of the first latch (322), a control input for receiving a control signal, and an output. The extension logic circuit (324) selectively delays the output of the first latch (322) in response to the control signal. The second latch (330) has an input coupled to the output of the extension logic circuit (324), a clock input for receiving a second clock signal, and an output for providing an output data signal.
