Overview
XR33180/81/83/84 3V to 5.
5V, 52Mbps, TSOT23 RS-485/RS-422 Receivers with ±15kV ESD Protection April 27, 2022 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.
The XR33181 is available in a 6-pin TSOT23 package and offers a active high receiver enable pin while the XR33183 has the same pinout but with active low enable pin.
The XR33184 is available in a 6-pin TSOT23 package with a I/O logic supply pin to ease the interface to MCU’s or FPGA’s that run off of different supply voltages.
The VL supply pin allows the XR33184 to interface to other devices running off of supplies from ranging from 1.
65V to VCC.
All XR3318x options operate up to a max data rate of 52Mbps, and have excellent propagation delay and skew characteristics making them a good choice for clock fanout or clock distribution systems.
