GENERAL DESCRIPTION
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 at minimum 96kΩ (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 XR3072X drivers are slew limited for reduced EMI and error-free communication over long or unterminated data cables. The devices with DE and RE pins include hot swap circuitry to prevent false transitions on the bus during powerup or live insertion, and can enter a 1nA low current shutdown mode for extreme power savings. The transceivers draw less than 600µA from a 3.3V supply, and typically only 300µA when idling with the receivers active. FEATURES
