The XR33058 is a high performance RS-485/RS-422 transceiver 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 receiver includes full fail-safe circuitry, guaranteeing a logic high receiver output when the receiver inputs are open, shorted or undriven. 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 XR33058 is a half-duplex transceiver offered in an 8-pin NSOIC package that operates at a maximum data rate of 20Mbps.

For RS-232 it is 50 feet (15 meters), or the cable length equal to a capacitance of 2500 pF, at a maximum transmission rate of 19.2kbps. When we reduce the baud rate, it allows for longer cable length. For Example:

Fail Safe is an attempt to keep the output of the RS-485 receiver to a known state. Transceivers may have standard fail safe or advanced / enhanced receiver fail safe features. Standard fail safe supports open inputs while enhanced fail safe transceivers such as the SP339 and XR34350 support open input, shorted input and undriven terminated lines without external biasing. See Application Note ANI-22 for more detail.
