XR5487E:5V Ultra High Speed RS-485/RS-422 PROFIBUS Transceivers, Advanced Failsafe, Hot Swap Protection, ±15kV ESD-Protected

The XR5486E-XR5488E family of RS-485 devices are designed for reliable, bidirectional communication on multipoint bus transmission lines. Each device contains one differential driver and one differential receiver. XR5488E is a half-duplex device while the other part numbers are full-duplex. All devices comply with TIA/EIA-485 and TIA/EIA-422 standards. Lead-free and RoHS compliant packages are available for all models. These devices are ruggedized for use in harsh operating conditions over the entire common mode voltage range from -7V to +12V. Receivers are specially designed to fail-safe to a logic high output state if the inputs are left un-driven or shorted. All RS- 485 bus-pins are protected against severe ESD events up to +/-15kV Air-Gap (IEC-61000-4-2), up to +/-8kV Contact Discharge (IEC-61000-4-2) and up to +/-15kV Human body Model. Drivers are protected from excess current flow caused by bus contention or output short-circuits by both an internal current limit and a thermal-overload shutdown. Devices are rated for    Industrial    (-40°C    to    +85°C)    operating temperatures. Receivers have exceptionally high input impedance, which places only 1/8th the standard load on a bus. Up to 256 transceivers may coexist while preserving full signal margin. All devices operate from a single 5.0V power supply and draw negligible quiescent power.  All versions except the XR5487E may independently enable and disable their driver and receiver and enter a low power shutdown mode if both driver and receiver are disabled. All outputs maintain high impedance in shutdown or when powered-off.
