1 GENERAL DESCRIPTION FEATURES The XR33032/35/38 family of high performance half duplex RS-485 transceivers are optimized to operate over a wide range of supply voltage, from +2.
8V to +5.
5V.
The analog bus pins can withstand direct shorts up to ±18V, and are protected against ESD events up to ±15kV.
In an isolated application it may be more efficient to use a remote power supply rather than generating an isolated supply at every node.
The XR33032/35/38 transceivers can operate with more than 2V IR drop in the cable when utilizing a remote 5V power supply.
The transceivers draw less than 600µA, and typically only 300µA when idling with the receivers active.
The receivers include full fail-safe circuitry, guaranteeing a logic-high receiver output when the receiver inputs are open, shorted, or undriven.
The receiver input impedance is 96k (1/8 unit load), allowing up to 256 devices on the bus while preserving the full signal margin.
 +2.
8V to +5.
5V Operating Range  ±18V Fault Tolerance on Analog Bus pins  Robust ESD (ElectroStatic Discharge) Protection:  ±15kV IEC 61000-4-2 Air Gap Discharge  ± 8kV IEC 61000-4-2 Contact Discharge  ±15kV Human Body Model  ± 4kV Human Body Model on non-bus pins  300µA Idle Current, 40nA Shutdown Current  Enhanced Receiver Fail-Safe Protection for Open, Shorted, or Terminated but Idle Data Lines  Hot-Swap Glitch Protection on DE and RE Pins  Driver Short Circuit Current Limit and Thermal Shutdown for Overload Protection  1/8th Unit Load Allows up to 256 Devices on Bus  Industry Standard 8 NSOIC Half Duplex Package The drivers are protected by short circuit detection as well as thermal shutdown, and maintain high impedance in shutdown or when powered off.
The XR33032 and XR33035 drivers are slew limited for reduced EMI and error-free communication over long or unterminated data cables.
The DE and RE pins include hot s...
