Hi e2e,
The data sheet for the TS3A4742 is unclear regarding the maximum allowable voltage at the IN pins with a single 3.3V supply. There are three pertinent sections: “6.1 Absolute Maximum Ratings" (we’re good here), “6.5 Electrical Characteristics (3-V supply)” (good here too), but the 3rd section “6.3 Recommended Operating Conditions” specifies Vin_max of 1.8V, which seems to contradicts section 6.1 and is somewhat unexpected.
Can the digital voltage be driven by 3.3V logic if the Vcc voltage is 3.3V?
Thanks,
DJ
