THVD1451DR

The THVD14xx is a series of noise-immune RS-485/RS-422 transceivers designed specifically to operate in harsh industrial environments. The bus pins of these devices can withstand high levels of IEC Electrical Fast Transients (EFT) and IEC Electrostatic Discharge (ESD) events, eliminating the need for additional system-level protection components.

Applications

• Motor drivers
