Exar Corporation XR33032
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.| Part No. | XR33032 |

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
