Each device contains one differential driver and one differential receiver. Devices comply with TIA/EIA-485 and TIA/EIA-422 standards and also meet the higher drive and tighter skew requirements of PROFIBUS applications. Lead-free and RoHS compliant packages are available for all models. PROFIBUS is in wide use in industrial control and automation applications and the SP1486E is ruggedized for use in harsh operating conditions. Receivers are specially designed to fail-safe to a logic high output state if the inputs are left un-driven or shorted. All RS485 bus-pins are protected against severe ESD events up to ±15kV Air-Gap and Human Body Model and up to ±8kV Contact Discharge IEC 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 to +85ºC or Extended -40 to +125ºC operating temperatures. Receivers have exceptionally high input impedance, which places only 1/8th the standard load on a shared bus. Up to 256 transceivers may coexist while preserving full signal margin. All devices operate from a single V power supply and draw negligible quiescent power. Both driver and receiver can be enabled and disabled independently and the device enters a low power shutdown mode if both driver and receiver are disabled. The bus-pin outputs of disabled modules are in high impedance state. The high impedance driver output is maintained over the entire commonmode voltage range from -7 to +12V.
