The SP3080E-SP3088E family of RS-485 devices are designed for reliable, bidirectional commu-
nication 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 num-
bers 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 +2V. 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 ±5kV (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 in-
dustrial (-40 to +85C) operating temperatures. Receivers have exceptionally high input impedance,
which places only /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 ver-
sions except the SP308E, SP3084E, and SP3087E 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.
