The SN65HVD78DGK from Texas Instruments is a high-performance half-duplex RS-485 transceiver operating at 3.3V. It supports signaling rates up to 50 Mbps, making it suitable for various industrial communication applications.
This transceiver is equipped with robust protection features, including ±12kV IEC 61000-4-2 contact discharge ESD protection and ±15kV HBM protection, ensuring reliability in harsh environments. The device operates across an extended industrial temperature range of -40°C to 125°C.
Key electrical characteristics include a wide common-mode voltage range of -7V to 12V and 80mV of receiver hysteresis for enhanced noise immunity. It supports up to 200 connected nodes on the bus and features 5V tolerant logic inputs, allowing compatibility with both 3.3V and 5V controllers. The SN65HVD78DGK is available in an 8-VSSOP package, designed for space-saving applications, and also offers SOIC for drop-in compatibility.
Low power consumption is another advantage, with a maximum supply current of 950 µA during operation and less than 2 µA standby supply current. The device also provides glitch-free power-up and power-down transitions.
