7.3.3 1.8V Logic Compatible Inputs

The TMUXS7614D has 1.8V logic compatible control for all logic control inputs. 1.8V logic level inputs allows the TMUXS7614D 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. Additionally, VL supports 1.8V – 5.5V, and SDO is based on VL. So no additional translator is needed to support SPI readback. For more information on 1.8V logic implementations, refer to Simplifying Design with 1.8V logic Muxes and Switches.
