The TMUX112x devices have 1.8V logic compatible control for all logic control inputs. The logic input thresholds scale with supply, but still provide 1.8V logic control when operating at 5.5V supply voltage. 1.8V logic level inputs allows the TMUX112x devices to interface with processors that have lower logic I/O rails and eliminates the need for an external translator, which saves both space and BOM cost. The current consumption of the TMUX112x devices increase when using 1.8V logic with higher supply voltage as shown in Figure 6-10.
