8.3.2 1.8-V Logic Compatible Inputs

The TS5MP646 has 1.8-V logic compatible digital inputs for switch control. Regardless of the VDD voltage the digital input thresholds remained fixed, allowing a 1.8-V processor GPIO to control the TS5MP646 without the need for an external translator. This saves both space and BOM cost.

An example setup for a system without a 1.8-V logic compatible input is shown in Figure 22. Here the supply mismatch between the process and its GPIO output and the supply to the switch require a translator.

With the 1.8 V logic compatibility in the TS5MP646, the translator is built in to the device so that the external components are no longer needed, simplifying the system design and overall cost.
