Document Table of Contents Binary Multiplexers

Binary multiplexers select inputs based on binary-encoded selection bits.

Device families featuring 6-input look up tables (LUTs) are perfectly suited for 4:1 multiplexer building blocks (4 data and 2 select inputs). The extended input mode facilitates implementing 8:1 blocks, and the fractured mode handles residual 2:1 multiplexer pairs.
