XR33055HD-F

The XR33052, XR33053, XR33055, and XR33058 (XR3305x) are a family of high performance RS - 485/RS - 422 devices 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 XR3305x receivers include full fail - safe circuitry, guaranteeing a logic - high receiver output when the receiver inputs are open, shorted or undriven. The XR33052/53/55 receiver input impedance is at least 120kΩ (1/10 unit load), allowing more than 320 devices on the bus. The XR33058 receiver input impedance is at least 30KΩ (1/2.5 unit load), allowing more than 80 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 power up or live insertion and can enter a 1nA low current shutdown mode for extreme power savings.

The XR33052/55/58 are half - duplex transceivers offered in an 8 - pin NSOIC package and operates at a maximum data rates of 250k, 1M and 20Mbps. The XR33053 is a full - duplex transceiver offered in a 14 - pin NSOIC package and operates at a maximum data rate of 1 Mbps.
