Abstract
A PDP data driver is provided in which input and output terminals are divided into a plurality of groups and a given group can be selected so as to output a high level. The PDP data driver is formed by a plurality of data driver ICs that are arranged. In an output control circuit of each data driver IC, input and output terminals are arranged in an order of a plurality of primary colors forming a screen and are divided into a plurality of groups. The output control circuit includes a first gate array and a second gate array in such a manner that gates of each array corresponds to the input and output terminals, respectively. For each of the groups, the first gate array is controlled to output input data without change or output a high level in accordance with a first control input and the second gate array is controlled to transfer all outputs of the first gate array without change or output a low level in accordance with a second control output.
