SP1486E
+5V, 20Mbps PROFIBUS RS485/RS422 Transceivers
Advanced Failsafe, 1/8th Unit Load, ±15kV ESD-Protected
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
ruggedized 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 ±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) or Extended (-40 to +125oC) operating temperatures. Receiv
-
ers 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 voltage range from -7 to +2V.
