•Industry standard package footprints
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. 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 +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 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 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 pre-
serving full signal margin.
All devices operate from a single 5.0V power supply and draw negligible quiescent power. All ver-
sions except the SP3081E, 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.
