SN65HVD37DR

The SN65HVD37 combines a robust differential driver and a receiver with high noise immunity to meet the demands of stringent industrial applications. The driver's differential outputs and receiver's differential inputs are separate pins, forming a bus port for full-duplex (4-wire) communication. The driver and receiver can be independently enabled and feature a wide common-mode voltage range, making this device suitable for multipoint applications over long cable runs. The SN65HVD37 is rated for an operating temperature range of -40℃ to 85℃.
