Our extensive transceiver portfolio includes RS-232, RS-485, RS-422, and multi protocol transceivers and spans a range of data rates and advanced features
Most of Exars RS232 transceivers are pin and spec compatible with popular industry standard devices for direct drop-in replacement or a reliable second source for high volume production. Our enhanced ESD (ElectroStatic Discharge) devices are suitable for rugged applications in harsh operating conditions; up to 15kV IEC 61000-4-2, and/or 15kV HBM (Human Body Model).
Our broad RS 485/422 portfolio ranges from industry standard slew limited transceivers to ultra high speed (52Mbps), as well as high differential output drive transceivers for specialty applications or harsh industrial environments. In addition, Exar has RS485 transceivers that are compliant to popular field bus standards, including PROFIBUS. Advanced features like hot swap/hot plug, enhanced receiver failsafe, and 15kV ESD (ElectroStatic Discharge) protection ensure reliable and robust data communication over long cable lengths.
