THVD2410: Hot swap RS-422

Kazuki Itoh

Part Number: THVD2410

Hi team,

Could you please let me know if these RS-422 driver and receiver are hot-swappable?

THVD2410DGKR
AM26LV32CNSR

If not, could you please suggest another hot swappable RS-422 parts?

Best regards,

Itoh

    Itoh-san,

    Both of these devices can technically work in a hot-swap application since they're power on behavior is only based on the power rails meeting the thresholds and no sequencing or configuration. However, the AM26LV32CNSR has less bus voltage protection integrated, and when swapping devices in and out on a powered bus, there may be voltage spikes due to inductance. This shouldn't be a problem that would stop it from working, but something to keep in mind when deciding on bus protection components.

    Regards,
