SN65HVD1792DR Description

Short technical summary and product information.

The Texas Instruments SN65HVD1792DR is a fault-protected transceiver designed for RS485 and RS422 communication interfaces. This device supports full-duplex operation and can achieve signaling rates of up to 1 Mbps.

 

Key electrical characteristics include a wide common-mode voltage range of -20V to 25V and fault protection up to ±70V. It is designed to withstand various fault conditions such as direct shorts to power supplies and mis-wiring. The transceiver supports up to 256 nodes on the bus and features a failsafe receiver for open-circuit, short-circuit, and idle-bus conditions.

 

Packaged in a 14-SOIC (Surface Mount) configuration, the SN65HVD1792DR operates within an industrial temperature range of -40°C to 105°C. Its low supply current and robust design make it suitable for demanding industrial and automotive applications requiring reliable serial communication.

 

This transceiver combines a differential driver and a differential receiver, operating from a single power supply. It is designed to survive overvoltage faults and ESD events, offering enhanced reliability in harsh environments.
