MaxLinear XR33038
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. The XR33032/35/38 transceivers can operate with more than 2V IR drop in the cable when utilizing a remote 5V power supply.GENERAL DESCRIPTION
FEATURES
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 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
