Overview
XR33152/56/58 ±60V Fault Tolerant 3.
0V to 5.
5V TIA-485/TIA-422 Transceivers Description The XR33152, XR33156 and XR33158 family of high performance TIA-485/TIA-422 devices are 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.
An extended ±25V common mode operating range allows for more reliable operation in noisy environments.
The receivers include full fail-safe circuitry, guaranteeing a logic high receiver output when the receiver inputs are open, shorted or undriven.
The XR33152 receiver input impedance is at least 120kΩ (1/10 unit load), allowing more than 320 devices on the bus.
The XR33156/58 receiver input impedance is at least 30kΩ (1/2.
5 unit load), allowing more than 80 devices on the bus.
The drivers are protected by short circuit detection as well as thermal shutdown and maintain high impedance in shutdown or when powered off.
The XR33152 driver is slew limited for reduced EMI and error-free communication over long or unterminated data cables.
The XR33152/56/58 family of high performance TIA-485/TIA-422 devices are designed for improved performance in noisy industrial environments and increased tolerance to system faults.
The devices with 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 1nA low current shutdown mode for extreme power savings.
