The TMUX1119 has 1.8V logic compatible control for the logic control input (SEL). The logic input threshold scales with supply but still provide 1.8V logic control when operating at 5.5V supply voltage. 1.8V logic level inputs allow the TMUX1119 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.
