DESCRIPTION
The SN65HVD37 bines 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) munications. The driver and receiver can be independently enabled, and feature a wide mon-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.
