Traditional CMOS multiplexer designs do not require the select lines to be mutually exclusive, but run the risk of requiring potentially high stacks which degrade performance. A basic FCMI multiplexer design reduces the risk of potentially high stacks, but requires the select lines to be mutually exclusive. Through a hybrid combination of these multiplexer design approaches, the overall performance is improved and the tie up/down feature is internal to the FCMI multiplexer without requiring the tie up/down pin to be mutually exclusive with the other select pins, at a minimal to zero increase in size.
