DESCRIPTION
The XR33180, XR33181, XR33183 and XR33184 are high performance RS-485/RS-422 receivers designed to meet the increasing system requirements found in today’s high performance serial communication applications. The receiver includes enhanced failsafe circuitry, guaranteeing a logic-high receiver output when the receiver inputs are open, shorted, or undriven. The XR33180/81/83/84 (XR3318x) receiver input impedance is at least 48kΩ (1/4 unit load), allowing more than 128 devices on the bus. The bus pins are ESD protected and pass IEC61000 level 4 (±15kV). This is a wide supply (3.0V to 5.5V) device that operates at a maximum data rate of 52Mbps and comes in very small 5-pin and 6-pin TSOT23 packages, making this standalone receiver ideal for high speed point-to-point RS-485 applications where space is a concern. The XR3318x offers several pinout options to maximize performance in different applications while maintaining a minimum pin count. The XR33180 is available in a 5-pin TSOT23 package with the receiver always enabled.
