0 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 wh...
