Abstract
A multiplexer circuit, converting parallel data into serial data and synchronized with a clock signal, has a plurality of multiplexer cells that receive the parallel data. Each of the multiplexer cells has a first load, a plurality of first conductivity type transistors, and a level-changing circuit. The first conductivity type transistors are connected in series between a first power source line and a second power source line, and the level-changing circuit changes a connection node of adjacent first conductivity type transistors to a level of the first power source line.
