Выписка из документа:
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. 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 swap circuitry to prevent false transitions on the bus during power-up or live insertion, and can enter a low current shutdown mode (40nA typically) for extreme power savings.
