Abstract

A multiplexer containing multiple cells sharing a common output line. The cells select one of multiple input bits. The output line is first charged to a first logical value (e.g., 0), and one of the cells drives the output line to a second logical value (1) if the corresponding input bit does not equal the first logical value. The remaining cells may not affect the output line. Due to such an implementation, the number of transistors may be reduced.
