8.3.3 1.8V Logic Compatible Inputs

The TMUXS1306A and TMUXS1307A support 1.8V logic compatible control for all logic control inputs. The logic input thresholds scale very slightly with supply but still provide 1.8V logic control when operating at 5.5V supply voltage. 1.8V logic level inputs allows the multiplexers to interface with processors that have lower logic I/O rails but is based on VDD voltage levels for logic output. The current consumption of the TMUXS1306A and TMUXS1307A devices increase when using 1.8V logic with higher supply voltage. For more information on 1.8V logic implementations, see also 1.8V Logic for Multiplexers and Signal Switches application brief.
