SN65HVD1786DR Description

Short technical summary and product information.

The SN65HVD1786DR from Texas Instruments is a fault-protected RS-485/RS-422 transceiver. It offers a signaling rate of up to 1 Mbps and operates over a wide common-mode voltage range of -20V to 25V, exceeding TIA/EIA-485 requirements.

 

This transceiver is designed to survive overvoltage faults, including direct shorts to power supplies and mis-wiring. It provides ±70V bus-pin fault protection and ±16kV HBM ESD protection. The device supports up to 256 nodes on the bus due to its reduced unit load.

 

Packaged in an 8-pin SOIC, the SN65HVD1786DR is suitable for surface mounting. It operates from a 4.5V to 5.5V supply and features a failsafe receiver for open-circuit, short-circuit, and idle-bus conditions. Its low supply current and glitch-free operation during power transitions make it a reliable choice for industrial communication systems.
