2015-12-01 Lowest Power RS-485 Transceiver from Exar Includes Low Voltage Interface and Features <3uA Standby Current

Exar announces the XR33202, a half-duplex, 20Mbps RS-485 (TIA/EIA-485) transceiver
optimized to operate over a wide 3V to 5.5V supply voltage range.  The transceiver
includes an adjustable low voltage logic interface and features the industry's lowest
standby current of 3uA (max), 0.05uA (typ). The device's wide operating voltage range,
flexible logic interface, and low standby current make it ideal for battery-powered and
multi-voltage systems.

The XR33202 exceeds the highest ESD rating of IEC 61000-4-2 Level 4. It also includes
protection features such as hot swap glitch, overload and enhanced receiver fail-safe for
open, shorted or terminated idle data lines.

Specified over an extended temperature range of -40oC to 125oC, the XR33202 is
offered in RoHS compliant, green/halogen free, space-saving 3mm x 3mm DFN package.

Summary of features:

  •     Wide 3.0V to 5.5V supply operation
  •     1.65V to 5.5V I/O logic interface VL pin
  •     <3uA (max) standby current
  •     20Mbps maximum data rate  
  •     Robust ESD (Electrostatic Discharge) protection for RS-485 bus pins
  •     -40°C to 125°C ambient operating temperature range
