SN65HVD22DRG4 Description

Short technical summary and product information.

The SN65HVD22DRG4 from Texas Instruments is an extended common-mode RS-485 transceiver. It is designed for bidirectional data transmission on multipoint twisted-pair cables, making it suitable for applications requiring reliable communication in harsh environments.

 

This transceiver features a half-duplex configuration with a signaling rate of up to 500kbps. It supports an extended common-mode voltage range of -20V to 25V, exceeding standard TIA/EIA-485 requirements. The device offers fault protection from -27V to 27V and can support up to 256 nodes on the bus due to its reduced unit load.

 

Key electrical characteristics include a supply voltage range of 4.5V to 5.5V and a receiver hysteresis of 130 mV. The operating temperature range is from -40°C to 85°C. The SN65HVD22DRG4 is available in an 8-SOIC package and is designed for surface mount applications.

 

Example applications include digital motor controllers, remote sensors and terminals, industrial process control, security stations, and environmental control systems. Its robust design makes it ideal for long-cable networks and other demanding industrial applications.
