Hi
When UART signal is 1.8V. Then for TRS3122E, VL=1.8V and VCC=3.3V. Does PIN14/PIN15 support 3.3V pull up in this application? Thanks!
Regards
David

Hi Hao
Customer board already come back and they use 3.3V pull up. They wander any risk about using 3.3V pull up and if it is a must to change to 1.8V pull up. Thanks!

David,
The abs max of these pins are 6V. Using 3.3V logic should not damage the IC. Please let me know if you have any questions.
