We are working on design that would use the STUSB4500L in an all +5V system. The host processor is also at +5V. Unfortunately the STUSB4500L list +4.5V as recommended operating levels for the IO. What would be the risk of using the outputs and I2C interfaces from the STUSB4500L being tied to +5V.?
The line that we would like to pull-up to +5V are:
SDA
SCL
ATTACH
ALERT
Using a translator isnt really an option. We are completely out of board space. And cost is an issue.
Please advise.
Thank you.
