General Description

These devices extend the RS-485 portfolio with a family of full-duplex transceivers with robust 3.3-V drivers and receivers and high levels of ESD protection.

The ESD protection includes > ±30-kV HBM and > ±12-kV IEC61000-4-2 contact discharge.

The large receiver hysteresis of the SN65HVD7x devices provides immunity to conducted differential noise and the wide operating temperature enables reliability in harsh operating environments.
