ADM1486
GENERAL DESCRIPTION
The ADM1486 is a differential line transceiver suitable
for high speed bidirectional data communication on
multipoint bus transmission lines. It is designed for
balanced data transmission, complies with EIA Standards
RS-485 and RS-422 and is recommended for PROFIBUS
applications. The part contains a differential line driver
and a differential line receiver. Both the driver and the
receiver may be enabled independently. When disabled or
with power off, the driver outputs are tristated.
The ADM1486 operates from a single +5 V power supply.
Excessive power dissipation caused by bus contention or
by output shorting is prevented by a thermal shutdown
circuit. This feature forces the driver output into a high
impedance state if during fault conditions a significant
temperature increase is detected in the internal driver
circuitry.
Up to 50 transceivers may be connected simultaneously on
a bus, but only one driver should be enabled at any time.
It is important therefore that the remaining disabled
drivers do not load the bus. To ensure this, the ADM1486
driver features high output impedance when disabled and
also when powered down.
This minimizes the loading effect when the transceiver is
not being utilized. The high impedance driver output is
maintained over the entire common-mode voltage range
from –7 V to +12 V.
The receiver contains a fail safe feature which results in a
logic high output state if the inputs are unconnected
(floating).
The ADM1486 is fabricated on BiCMOS, an advanced
mixed technology process combining low power CMOS
with fast switching bipolar technology. All inputs and
outputs contain protection against ESD; all driver outputs
feature high source and sink current capability. An epi-
taxial layer is used to guard against latch-up.
The ADM1486 features extremely fast switching speeds.
Minimal driver propagation delays permit transmission at
data rates up to 50 Mbits/s while low skew minimizes
EMI interference.
The part is fully specified over the commercial and indus-
trial temperature range and is available in an 8-lead
DIL/SOIC/μSOIC package.
