Hi Expert,

Want to double check it, If the VCC is 1.8V, output pull high voltage is 3.3V, does it work? Thanks!

Hi Jerry,

It should work, I suggest I fairly large pull-up to avoid any overshoot causing it to go above 3.3 V.

Hi Dylan,
So, maybe 100Kohm for the pull high resistor?

Hi Jerry,

Yes that's a good value. If you need a faster transition rate you can lower the value, I'd just stay over 47Kohm.
