The SN65HVD37DR is a low-power, full duplex RS-485 driver and receiver integrated circuit (IC), manufactured by Texas Instruments. This IC can be used in applications where reliable communication is required from one point to multiple points on a multi-point serial bus. Its operating voltage window supports 3.3V signaling and logic levels. It has 5 kV isolation from the data cable, an adjustable receiver threshold over a wide range, and a driver output enable that allows multiple drivers to share the same bus line, reducing the number of interface chips. Another key feature is the large ±30V output swing that allows superior signal quality. Additional features of the SN65HVD37DR include slew-rate control to eliminate reflection-induced ground bounce and data-dependent skew on the line. This device is designed to use low power consumption, with the receiver section consuming only 1.4mA.
