The SP485CS-L is a half-duplex Differential Transceiver meets the requirements of RS-485 and RS-422. Fabricated with an Exar proprietary BiCMOS process, this product requires a fraction of the power of older bipolar designs. The RS-485 standard is ideal for multi-drop applications and for long-distance interfaces. RS-485 allows up to 32 drivers and 32 receivers to be connected to a data bus, making it an ideal choice for multi-drop applications. Since the cabling can be as long as 4000ft, RS-485 transceivers are equipped with a wide (-7 to 12V) common mode range to accommodate ground potential differences. Because RS-485 is a differential interface, data is virtually immune to noise in the transmission line. The driver outputs of the transceiver are differential outputs meeting the RS-485 and RS-422 standards. With worst case loading of 54R across the differential outputs, the drivers can maintain greater than 1.5V voltage levels.
