GENERAL DESCRIPTION
This minimizes the loading effect when the transceiver is not being
used. The high impedance driver output is maintained over the
entire common-mode voltage range from –7 V to +12 V.
The ADM485 is a differential line transceiver suitable for high
speed bidirectional data communication on multipoint bus trans-
mission lines. It is designed for balanced data transmission and
complies with EIA Standards RS-485 and RS-422. The part
contains a differential line driver and a differential line receiver.
Both the driver and the receiver may be enabled independently.
When disabled, the outputs are three-stated.
The receiver contains a fail-safe feature that results in a logic
high output state if the inputs are unconnected (floating).
The ADM485 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 epitaxial layer is used to guard against latch-up.
The ADM485 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 condi-
tions a significant temperature increase is detected in the internal
driver circuitry.
The ADM485 features extremely fast switching speeds. Minimal
driver propagation delays permit transmission at data rates up to
5 Mbps while low skew minimizes EMI interference.
The part is fully specified over the commercial and industrial
temperature range and is available in PDIP, SOIC, and small
footprint MSOP packages.
Up to 32 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 ADM485 driver features high output imped-
ance when disabled and when powered down.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although the
ADM485 features proprietary ESD protection circuitry, permanent damage may occur on devices
subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended
to avoid performance degradation or loss of functionality.

APPLICATION INFORMATION
Differential Data Transmission
on the bus. Only one driver can transmit at a particular time, but
multiple receivers may be enabled simultaneously.
Differential data transmission is used to reliably transmit data at
high rates over long distances and through noisy environments.
Differential transmission nullifies the effects of ground shifts and
noise signals that appear as common-mode voltages on the line.
There are two main standards approved by the Electronics
Industries Association (EIA) that specify the electrical charac-
teristics of transceivers used in differential data transmission.
As with any transmission line, it is important that reflections be
minimized. This can be achieved by terminating the extreme ends
of the line using resistors equal to the characteristic impedance
of the line. Stub lengths of the main line should also be kept as
short as possible. A properly terminated transmission line appears
purely resistive to the driver.
RT
RT
The RS-422 standard specifies data rates up to 10 MBaud and
line lengths up to 4000 ft. A single driver can drive a transmission
line with up to 10 receivers.
D
D
In order to cater for true multipoint communications, the
RS-485 standard was defined. This standard meets or exceeds
all the requirements of RS-422 but also allows for up to 32
drivers and 32 receivers to be connected to a single bus. An
extended common-mode range of –7 V to +12 V is defined. The
most significant difference between RS-422 and RS-485 is the
fact that the drivers may be disabled, thereby allowing more
than one (32 in fact) to be connected to a single line. Only one
driver should be enabled at a time, but the RS-485 standard
contains additional specifications to guarantee device safety in
the event of line contention.

Thermal Shutdown
Table III. Comparison of RS-422 and RS-485 Interface Standards
The ADM485 contains thermal shutdown circuitry that protects the
part from excessive power dissipation during fault conditions.
Shorting the driver outputs to a low impedance source can result
in high driver currents. The thermal sensing circuitry detects the
increase in die temperature and disables the driver outputs. The
thermal sensing circuitry is designed to disable the driver outputs
when a die temperature of 150°C is reached. As the device cools,
the drivers are re-enabled at 140°C.

maximum baud rate operation. The driver is well balanced, ensuring
distortion free transmission.

Cable and Data Rate
Another important specification is a measure of the skew between
the complementary outputs. Excessive skew impairs the noise
immunity of the system and increases the amount of electro-
magnetic interference (EMI).
The transmission line of choice for RS-485 communications
is a twisted pair. Twisted pair cable tends to cancel common-
mode noise and causes cancellation of the magnetic fields gener-
ated by the current flowing through each wire, thereby reducing
the effective inductance of the pair.
Receiver Open-Circuit Fail-Safe
The receiver input includes a fail-safe feature that guarantees
a Logic High on the receiver when the inputs are open circuit
or floating.
The ADM485 is designed for bidirectional data communications
on multipoint transmission lines. A typical application showing
a multipoint transmission network is illustrated in Figure 5.
An RS-485 transmission line can have as many as 32 transceivers
