  • THVD1429: Undershoot of DE/RE port

    TI Thinks Resolved
    Part Number: THVD1429 Dear Technical Support Team, Upon seeing the input waveform of the DE/RE report, we observed a waveform exceeding the maximum rating for a brief period (less than 10ns). This duration is likely too short for the IC's body diode…
