Exar Corporation XR33053
The XR33053 is a high performance TIA-485/TIA-422 device designed for improved performance in noisy industrial environments and increased tolerance to system faults. The analog bus pins can withstand direct shorts up to ±60V and are protected against ESD events up to ±15kV HBM. The receiver includes full fail-safe circuitry, guaranteeing a logichigh receiver output when the receiver inputs are open, shorted or undriven.| Part No. | XR33053 |

DESCRIPTION
An extended ±25V common mode operating range allows for more reliable operation in noisy environments. The XR33053 receiver input impedance is at least 120kΩ (1/10 unit load), allowing more than 320 devices on the bus. The driver is protected by short circuit detection as well as thermal shutdown and maintains high impedance in shutdown or when powered off. The 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.FEATURES
