8.3.3 1.8 V Logic Compatible Inputs

The SN3257-Q1 has 1.8-V logic compatible control inputs. Regardless of the VDD voltage, the control input thresholds remain fixed, allowing a 1.8-V processor GPIO to control the SN3257-Q1 without the need for an external translator. This saves both space and BOM cost. For more information on 1.8 V logic implementations, refer to Simplifying Design with 1.8 V logic Muxes and Switches.
