The XR33202 is a high performance TIA-485/TIA-422 transceiver designed to meet the increasing system requirements found in today’s portable/handheld, process control and industrial equipment environments. This is a wide supply (3.0V to 5.5V) device that operates at maximum data rate of 20Mbps and features a 1.65V to 5.5V I/O logic supply, simplifying multi-voltage system interfacing requirements.
The receiver includes full fail-safe circuitry, guaranteeing a logic high receiver output when the receiver inputs are open, shorted or undriven. The XR33202 receiver input impedance is at least 96kΩ (1/8 unit load), allowing more than 256 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 XR33202 does not have slew limiting and is intended for high speed applications requiring data rates up to 20Mbps.
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 1μA low current shutdown mode for extreme power savings.
The XR33202 is a half-duplex device that operates at max data rates 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.
