Each device contains one differential driver and one differential receiver. SP3082E, SP3085E and SP3088E are half-duplex devices; other part numbers are full-duplex. All devices ply with TIA/EIA-485 and TIA/EIA-422 standards. Lead-free and Ro HS pliant packages are available for all models. These devices are ruggedized for use in harsh operating conditions over the entire mon-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 ±15k V (Air-Gap and Human Body Model) and up to ±8k V Contact Discharge (IEC 10004-2). Drivers are protected from excess current flow caused...
