The SP4082E is designed for reliable, bidirectional communication on multipoint bus transmission
lines. The device contains one differential driver and one differential receiver. It is a half-duplex de-
vice. The device complys with TIA/EIA-485 and TIA/EIA-422 standards. Lead-free and RoHS compli-
ant packages are available.
This device is ruggedized for use in harsh operating conditions over the entire common-mode volt-
age range from -7V to +2V. Receivers are specially designed to fail-safe to a logic high output state
if the inputs are un-driven or shorted. All RS-485 bus-pins are protected against severe ESD events
up to ±15kV (Human Body Model). 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 +85C) operating temperatures. Receivers have exceptionally
high input impedance, which places only /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
device has an independent enable and disable for the driver and receiver and will enter a low power
shutdown mode if both driver and receiver are disabled. All outputs maintain high impedance during
shutdown or when powered-off.
