PROFIBUS applications
SP486E is a half duplex differential line transceiver suitable for high speed bidirectional commu-
nication on multipoint bus transmission lines. Each device contains one differential driver and one
differential receiver. Devices comply with TIA/EIA-485 and TIA/EIA-422 standards and also meet the
higher drive and tighter skew requirements of PROFIBUS applications. Lead-free and RoHS compli-
ant packages are available for all models.
PROFIBUS is in wide use in industrial control and automation applications and the SP486E is rug-
gedized for use in harsh operating conditions. Receivers are specially designed to fail-safe to a logic
high output state if the inputs are left un-driven or shorted. All RS485 bus-pins are protected against
severe ESD events up to ±5kV (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 +85C) operating temperature. 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 5.0 V power supply and draw negligible quiescent power. Both driver
and receiver can be enabled and disabled independently and the device enters a low power shutdown
mode if both driver and receiver are disabled. The bus-pin outputs of disabled modules are in high
impedance state. The high impedance driver output is maintained over the entire common-mode volt-
age range from -7 to +2V.
