DESCRIPTION

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.
