DESCRIPTION

The SP3080E is designed for reliable, bidirectional communication on multipoint bus transmission

lines. The device contains one differential driver and one differential receiver. The SP3080E is a

full-duplex device. All devices comply with TIA/EIA-485 and TIA/EIA-422 standards. Lead-free and

RoHS compliant packages are available for all models.

This device is ruggedized for use in harsh operating conditions over the entire common-mode volt-

age range from -7V to +12V. The receiver is a 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). The driver is protected from excess current ﬂow caused by bus contention or output short-circuits

by both an internal current limit and a thermal-overload shutdown. The device is rated for industrial

(-40 to +85ºC) or extended (-40 to +125ºC) operating temperatures. The receiver has exceptionally

high input impedance, which places only 1/8th the standard load on a shared bus. Up to 256 trans-

ceivers may coexist while preserving full signal margin.

The device operates from a single 5.0V power supply and draws negligible quiescent power. The

SP3080E may independently enable and disable its driver and receiver and enter a low power shut-

down mode if both driver and receiver are disabled. The output maintains high impedance in shut-

down or when powered-off.
