8.3.3 1.8 V Logic Compatible Inputs

The TMUX1237 has 1.8-V logic compatible control for the logic control input (SEL). The logic input threshold scales with supply but still provides 1.8-V logic control when operating at 5.5 V supply voltage. 1.8-V logic level inputs allow the TMUX1237 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.
