RS-485 Line Drivers and Receivers, EXAR Exar has a broad range of RS-485 transceivers that are compliant to popular field bus standards, including PROFIBUS. Some may have advanced features like enhanced receiver failsafe, and 15kV ESD protection ensuring reliable and robust data communication over long cable lengths. Exar&#146;s high ESD devices are qualified up to +/-15kV IEC 61000-4-2, and +/-15kV HBM (Human Body Model). The EXAR RS 485 transceivers can be used for RS 422 also.<BR/>Most of Exar&#146;s serial transceivers are pin and spec compatible with popular industry devices for direct drop-in second source replacement.

RS-232 Line Drivers and Receivers, EXAR Exar offers a wide range of RS232 serial communication standard (also known as TIA/EIA-232) devices. They span over a range of data rates from 20kbps to 1Mbps, including the popular 120kbps and 250kbps speeds. RS-232 transceivers operate from a single 5V supply, and many can operate with a supply voltage as low as 3V<BR/>The enhanced ESD (ElectroStatic Discharge) up to +/-15kV IEC 61000-4-2, and/or +/-15kV HBM (Human Body Model)<BR/>Most of Exar&#146;s devices are pin and spec compatible with popular industry standard devices for direct drop-in replacement
