The THVD1454 operates from 3 V to 5.5 V bus supply. Internal ESD protection circuits on bus pins protect the transceiver against Electrostatic Discharges (ESD) according to IEC 61000-4-2 of up to ±8 kV (Contact Discharge), ±15 kV (Air Gap Discharge) and against electrical fast transients (EFT) according to IEC 61000-4-4 of up to ±4 kV.
