High-speed RS-485 receivers for industrial applications
Exar’s latest high-speed RS-485/RS-422 receivers, XR33180, XR33181, XR33183, and XR33184 occupy a 3 x 3 mm footprint and feature 52 Mbps data rates, 15 nsec propagation delay and 2 nsec maximum receiver skew. This family is suited for high performance industrial applications such as multi-drop clock distribution, telecom networking, robotic control, process automation and local area network applications.
XR3318x chips operate from either a 3.3V or 5V supply and are available in 5-pin and 6-pin TSOT23 packages, 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 ±15 kV ESD protection on the receiver inputs, exceed the highest ESD rating of IEC 61000-4-2 and operate over an extended temperature range of -40°C to +125°C. Pricing starts at $0.55 (1000).
