Description
AI
The SN65HVD37 combines a robust differential driver and a receiver with high noise immunity for demanding industrial applications. The driver differential outputs and the receiver differential inputs are separate pins, to form a bus port for full-duplex (four-wire) communications. The driver and receiver can be independently enabled, and feature a wide common-mode voltage range, making this device suitable for multi-point applications over long cable runs. The SN65HVD37 is characterized over the temperature range of –40ºC to 85 ºC.
