SP1486E is a half duplex differential line transceiver suitable for high speed bidirectional commu- nication on multipoint bus transmission lines. 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 compli- ant packages are available for all models.PROFIBUS is in wide use in industrial control and automation applications and the SP\u0018486E is rug- gedized 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 1000-4-2). 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) operating temperature. 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 5.0 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 common-mode volt- age range from -7 to +12V.For technical support or help choosing a product please email Exar’s Serial Technical Support group at:?serialtechsupport@exar.com.
