SN65HVD1781D Description

Short technical summary and product information.

The SN65HVD1781D from Texas Instruments is a fault-protected RS-485 transceiver featuring robust protection against overvoltage faults, including direct shorts to power supplies and mis-wiring. It operates with a supply voltage range of 3.3V to 5V and supports a maximum signaling rate of 10 Mbps.

 

This transceiver is designed for half-duplex communication and can accommodate up to 320 nodes on the bus. It offers a wide fault protection range of ±70V and ±16kV HBM protection on bus pins. The device also includes failsafe receiver functionality for open-circuit, short-circuit, and idle-bus conditions.

 

Available in an 8-pin SOIC package, the SN65HVD1781D is suitable for surface mount applications. Its low power consumption, with a standby supply current of 1 µA and a quiescent current of 4 mA during operation, makes it an efficient choice for various industrial and automotive communication systems.
