Based on VCC = 3.3V, Vinh,max = 0.7*VCC = 2.31V & Vinl,min = 0.3*VCC = 0.99V

I suppose above also applies to VCC = 5V? How about typical values?

Hi PY

UCC21732 has the same VINH and VINL specs as the other drivers in the UCC217xx-Q1 family. Please refer to the E2E post in this link for the threshold information: https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1065894/ucc21759-q1-input-voltage-thresholds-of-the-ucc21759-q1-over-different-vcc-voltages/3943809#3943809

Best regards,
