Overview
SP3082E/ SP3083E/ SP3084E/ SP3085E/ SP3088E Data Sheet Advanced-Failsafe RS-485 / RS-422 Transceivers 1/8th Unit Load, Slew-Rate Limited, ±15kV ESD-Protected General Description Features The SP3082E-SP3088E 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.
The SP3082E, SP3085E and SP3088E are half-duplex devices; 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 and Human Body Model) and up to ±8kV Contact Discharge (IEC 61000-4-2).
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 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 5.
0V power supply and draw negligible quiescent power.
All versions except the SP3084E 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.
