RS-485/RS-422 Receivers support high-speed communications.

Press Release Summary:



Available in 5- and 6-pin TSOT23 packages with 3 x 3 mm footprint, Models XR33180, XR33181, XR33183, and XR33184 feature 52 Mbps data rates, 15 ns propagation delay, and 2 ns max receiver skew. XR33184 includes low voltage logic pin that eliminates need for level shifter when interfacing to MCUs or FPGAs that run off lower supply voltages. Operating from -40 to +125°C with 3.3 or 5 V supply, all models provide ±15 kV ESD protection on receiver inputs and exceed ESD rating of IEC 61000-4-2.

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



- Provides compatibility with low- voltage logic down to 1.65V to simplify multi-voltage system design

- Offers high 52Mbps data rate, fast propagation delay and excellent package-to-package skew times for improved operation in clock distribution systems 

- ±15kV ESD protection reduces ESD-related failures



Fremont, CA – Exar Corporation (NYSE: EXAR), a leading supplier of analog mixed-signal products serving the industrial, infrastructure, automotive and audio video markets, today 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.



"These stand-alone receivers add point-to-point operability and a tiny footprint option to our broad family of RS-485 serial transceivers," said Dale Wedel, VP of high performance analog at Exar. "With features like the enhanced ESD protection, a logic supply pin, true fail-safe circuitry and enhanced receiver failsafe protection, these receivers meet the growing demands of today’s high performance serial communication applications."



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.



The XR33180, XR33181, XR33183, and XR33184 are available now in a RoHS compliant and green, TSOT23-5 and TSOT23-6 packages. Pricing starts at $0.55 in quantities of 1,000. For more information, visit www.exar.com/products/interface/serial-transceivers/rs485-422
