SN65HVD78DGKR Description

Short technical summary and product information.

The SN65HVD78DGKR from Texas Instruments is a 3.3V half-duplex RS-485 transceiver. It supports signaling rates up to 50 Mbps, making it suitable for various industrial communication applications. The device features IEC ESD protection, rated at ±12000 V contact discharge, enhancing its robustness in harsh environments.

 

This transceiver operates within an extended industrial temperature range of -40°C to 125°C and requires a supply voltage between 3V and 3.6V. It includes features like 80 mV of receiver hysteresis for improved noise immunity and low unit loading, allowing over 200 nodes on a single bus. The SN65HVD78DGKR is available in an 8-VSSOP package, designed for space-saving applications, and also offers SOIC for drop-in compatibility.

 

Key electrical characteristics include a common-mode range of -7V to 12V and fault protection from -13V to 16.5V. The device also boasts low power consumption with a maximum supply current of 950 µA during operation and less than 2 µA standby supply current. Its 5-V tolerant logic inputs ensure compatibility with both 3.3V and 5V controllers.
