The device and method for multiplexing cells inputted to an asynchronous transmission mode using an input buffer according to the amount of traffic. The cell multiplexing device of an asynchronous transmission mode, includes: a buffer portion which include cell buffers corresponding to input ports, for storing cells received through the input ports; counters which have the number corresponding to that of the buffers, for storing the number of cells to be stored in the buffers a unit clock unit for determining for the counters a count unit of cells to be stored in the buffers; selector for outputting control signals to select buffers having their maximum values by comparing the values of the counters with each other; and a unit for inputting the output of the buffer unit and multiplexing the input cells according to the control signal, wherein the generation of buffer overflow is prevented by primarily processing the cells from a buffer where the most cells are stored.
