XR33180/81/83/84 3V to 5.5V, 52Mbps, TSOT23 RS-485/RS-422 Receivers with 15kV ESD Protection Description FEATURES The XR33180, XR33181, XR33183 and XR33184 are high performance Max 52Mbps data rate RS-485/RS-422 receivers designed to meet the increasing system Wide 3.0V to 5.5V supply operation Robust Electrostatic Discharge (ESD) requirements found in todays high performance serial communication protection for RS-485 bus pins applications. 15kV human body model The receiver includes enhanced failsafe circuitry, guaranteeing 15kV IEC61000-4-2 air discharge a logic-high receiver output when the receiver inputs are open, 8kV IEC61000-4-2 contact shorted, or undriven. The XR33180/81/83/84 (XR3318x) receiver discharge Enhanced receiver failsafe protection for input impedance is at least 48k (1/4 unit load), allowing more than open, shorted, or terminated but idle data 128 devices on the bus. The bus pins are ESD protected and pass lines IEC61000 level 4 (15kV). -40C to 125C ambient operating This is a wide supply (3.0V to 5.5V) device that operates at a maximum temperature range data rate of 52Mbps and comes in very small 5-pin and 6-pin TSOT23 Lead-free (RoHS 6) TSOT23-5 and TSOT23-6 packaging packages, making this standalone receiver ideal for high speed Absolute minimum pin count option, point-to-point RS-485 applications where space is a concern. XR33180 (5-pin TSOT23) The XR3318x offers several pinout options to maximize performance Tri-state RO options, XR33181 and in different applications while maintaining a minimum pin count. The XR33183 XR33180 is available in a 5-pin TSOT23 package with the receiver Adjustable I/O supply option to help always enabled. The XR33181 is available in a 6-pin TSOT23 package interfacing to lower voltage logic, XR33184 and offers a active high receiver enable pin while the XR33183 has the APPLICATIONS same pinout but with active low enable pin. The XR33184 is available Clock distribution in a 6-pin TSOT23 package with a I/O logic supply pin to ease the Robotic control interface to MCUs or FPGAs that run off of different supply voltages. Space constrained systems The V supply pin allows the XR33184 to interface to other devices L Security camera networks running off of supplies from ranging from 1.65V to V . CC Industrial and process control equipment 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.
