Disclosed herein is a data driver for a matrix display device, which includes a shift register circuit for sequentially shifting a sampling start pulse in response to a clock signal, to produce a plurality of sampling signals, a plurality of sample/hole circuits each sampling display data in response to a sampling signal applied thereto. This driver further includes a switching circuit which transfers each of the sampling signals to an associated one of the sample/hold circuits in a sequential-sampling mode and the selected ones thereof to the sample/hold circuits such that one of the selected sampling signals is supplied in common to at least two of the sample/hold circuits in a simultaneous circuits.
