Abstract
An integrated circuit and its using method. The integrated circuit having a serial-parallel converter and a driver unit is further provided with a setting circuit which is responsive to a selection signal value for setting the number of shift stages of the serial-parallel converter. When serial data consisting of a number of bits exceeding the setup stage count is input, the serial-parallel converter outputs data as overflow serial data in order starting at the first input bit of the serial data. A plurality of the integrated circuits are cascaded so that overflow serial data output from the integrated circuit at a preceding stage is supplied to the integrated circuit at the following stage as serial data to be converted into parallel data. The same selection signal value is supplied to each of the integrated circuits.
