High-Speed, Small Footprint RS-485 Receivers for Industrial Applications

Exar Corporation announced a family of high-speed RS-485/RS-422 receivers that accommodate the complex demands of next generation high-speed serial communications designs.  The XR33180, XR33181, XR33183, and XR33184 occupy a 3mm x 3mm footprint and feature 52Mbps data rates, fast 15ns propagation delay and 2ns maximum receiver skew.  This family is best suited for high performance industrial applications such as multi-drop clock distribution, telecom networking, robotic control, process automation and local area network applications. 

The XR33180/81/83/84 (XR3318x) operate from either a 3.3V or 5V supply and are available in tiny 5-pin and 6-pin TSOT23 packages, ideal for high-speed point-to-point RS-485 applications where space is a concern.  The XR33184 includes a low voltage logic pin that eliminates the need for a level shifter when interfacing to MCUs or FPGAs that run off of lower supply voltages.

All devices feature ±15kV ESD protection on the receiver inputs and exceed the highest ESD rating of IEC 61000-4-2 and operate over an extended temperature range of -40°C to +125°C.
