Hi expert,
Referring to USB specfication Rev2.0 "7.1.1 USB Driver Characteristics", The USB port can withstand voltages from -1.0 to 4.6V.
In the other hand, Referring to TS3USB31E datasheet "6.1 Absolute Maximum Ratings", Absolute Maximum Ratings of HSD+, HSD–, D+, D–(when VCC=3.3V) voltage are defined from -0.5V to 3.6V(=VCC+0.3).
If TS3USB31E receives waveform with undershoot of -1.0V or overshoot of 4.6V(when TS3USB31E's VCC=3.3V), Will TS3USB31E be damaged?
