SN65HVD78DR Description

Short technical summary and product information.

The SN65HVD78DR from Texas Instruments is a 3.3V half-duplex RS-485 transceiver featuring IEC ESD protection and a maximum signaling rate of 50 Mbps. This device is suitable for applications requiring reliable data transmission in harsh environments, operating across an extended industrial temperature range of -40°C to 125°C.

 

Key electrical characteristics include a common-mode voltage range of -7V to 12V and receiver hysteresis of 80 mV for enhanced noise immunity. It supports up to 200 nodes on the bus and features 5V tolerant logic inputs, allowing compatibility with both 3.3V and 5V controllers. The transceiver also boasts low power consumption with a standby supply current of less than 2 µA.

 

Available in an 8-SOIC package, the SN65HVD78DR is designed for surface mount applications. It provides robust bus I/O protection, including ±15 kV HBM and ±12 kV IEC 61000-4-2 contact discharge protection, ensuring data integrity in demanding conditions. The device offers glitch-free power-up and power-down transitions.
