TMUX8108/TMUX8109 Multiplexers Texas Instruments TMUX8108/TMUX8109 Multiplexers are modern high voltage capable analog multiplexers in 8:1 (single-ended) and 4:1 (differential) configurations. The devices work well with dual supplies, a single supply, or asymmetric supplies up to a maximum supply voltage of 100V. The TMUX810x devices provide consistent analog parametric performance across the entire supply voltage range. The TMUX8108 and TMUX8109 support bidirectional analog and digital signals on the source (Sx) and drain (Dx) pins.
