Datasheet Summary

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.

Features

  • 3.0V to 5.5V operation.
  • ±60V fault tolerance on analog bus pins.
  • Extended ±25V common mode operation.
  • Robust ESD protection: ±15kV HBM (bus pins) ± 4kV HBM (non-bus pins).
  • 1.65V to 5.5V logic Interface VL pin (full-duplex package option).
  • Invert control to correct for reversed bus pins.
  • Enhanced receiver fail-safe protection for open, shorted or terminated but idle data lines.
  • Hot swap glitch protection on DE and RE.

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.
