A 1:10 demultiplexer using a comma code is provided to reduce the number of transistors and power consumption largely while fully guaranteeing correct data synchronization and fast operation by detecting data start information based on the comma code instead of a comma string. A demultiplexer(310) changes 1-bit data of serial data into 2-bit data through 1:2 demultiplexing by receiving the serial data and a clock representing input timing of the serial data. A comma detector(320) stores 2-bit data to two shift registers(322a,322b), detects a comma code representing start of the data by using the data stored in the shift registers, and generates a data synchronization signal and a data arrangement state signal when the comma code is detected. Two multiplexers(332a,332b) rearrange 2-bit data received from the command detector by using the data arrangement state signal. A word arranger(330) stores the data received from the multiplexers to two 5-bit shift registers(334a,334b) and samples 10-bit data stored to two 5-bit shift registers by using the data synchronization signal.
