FREMONT, Calif., Oct. 18, 2016 /PRNewswire/ -- 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 transmitters that combine low power, high performance, small packaging and high ±15kV ESD protection.  This family is best suited for industrial applications such as multi-drop clock distribution, telecom networking, robotic control, process automation and local area network applications.

The XR33193, XR33194 and XR33195 operate from a 3.3V supply and draw only 180µA (375µA maximum) of supply current.  All transmitters feature a shutdown mode that consumes less than 2µA whenever the transmitters are disabled.  The family is available in tiny 6-pin TSOT23 packages, ideal for high-speed point-to-point RS-485 applications where space is a concern. 

The XR33193/94/95 occupy a 3mm x 3mm footprint and feature 250kbps, 2.5Mbps and 20Mbps data rates. The XR33193 and XR33194 have slew-limited outputs for reduced EMI and error-free communication over long or improperly terminated data cables and multi-drop applications with unterminated stubs. The XR33195 features fast 25ns propagation delay and 5ns driver-output skew. All three RS-485 transmitters feature ±15kV ESD protection on the driver outputs and operate over an extended temperature range of -40°C to +125°C.  They also offer hot-swap glitch protection allowing live insertion without driving invalid data onto shared busses.

"These stand-alone drivers complement our recently announced family of RS-485 receivers the XR33180/81/83/84," said Dale Wedel, VP of high performance analog at Exar. "This tiny driver/receiver chipset is a simple solution for point-to-point RS-485 serial communication."

Pricing and Availability:
The XR33193, XR33194 and XR33195 are available now in an RoHS compliant and green TSOT23-6 packages. Pricing starts at $0.55 in quantities of 1,000. For more information, visit https://www.exar.com/products/interface/serial-transceivers/rs485-422
