9.3.3 1.8 V Logic Compatible Inputs

The TMUX1308-Q1 and TMUX1309-Q1 support 1.8-V logic compatible control for all logic control inputs. The logic input thresholds scale with supply but still provide 1.8-V logic control when operating at 5.5-V supply voltage. 1.8-V logic level inputs allows the multiplexers to interface with processors that have lower logic I/O rails and eliminates the need for an external voltage translator, which saves both space and BOM cost. The current consumption of the TMUX1308-Q1 and TMUX1309-Q1 devices increase when using 1.8-V logic with higher supply voltage. For more information on 1.8-V logic implementations, refer to Simplifying Design with 1.8 V logic Muxes and Switches.
