Each device contains one differential driver and one differential receiver. Devices ply 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 Ro HS pliant 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 ±15k V (Air-Gap and Human Body Model) and up to ±8k V 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...
