GENERAL DESCRIPTION
The ADM488A and ADM489A are low power, differential line
transceivers suitable for communication on multipoint bus
transmission lines. They are intended for balanced data
transmission and comply with both RS-485 and RS-422
standards of the Electronics Industries Association (EIA). Both
products contain a single differential line driver and a single
differential line receiver, making them suitable for full-duplex
data transfer. The ADM489A contains an additional receiver
and driver enable control.
The input impedance is 12 kΩ, allowing 32 transceivers to be
connected on the bus. The ADM488A/ADM489A operate from
a single 5 V ± 10% power supply.

RO
Excessive power dissipation that is caused by bus contention or
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.
The receiver contains a fail-safe feature that results in a logic
high output state if the inputs are unconnected (floating).
The ADM488A/ADM489A are fabricated on BiCMOS, an
advanced mixed technology process combining low power
CMOS with fast switching bipolar technology.
The ADM488A/ADM489A are fully specified over the industrial
temperature range and are available in SOIC and MSOP packages.

THEORY OF OPERATION
The ADM488A/ADM489A are ruggedized RS-485 transceivers
that operate from a single 5 V supply. They contain protection
against radiated and conducted interference and are ideally suited
for operation in electrically harsh environments or where cables
can be plugged/unplugged. They are also immune to high RF
field strengths without special shielding precautions.
The ADM488A/ADM489A are intended for balanced data
transmission and comply with both EIA RS-485 and RS-422
standards. They contain a differential line driver and a differential line receiver, and are suitable for full-duplex data transmission.
the slew rate is controlled by the ADM488A/ADM489A and
reflections are minimized.
The communications network can be extended to include
multipoint connections, as shown in Figure 22. As many as
32 transceivers can be connected to the bus.
Table 6 and Table 7 show the truth tables for transmitting and
receiving.
Table 6. Transmitting Truth Table
Inputs
The input impedance on the ADM488A/ADM489A is 12 kΩ,
allowing up to 32 transceivers on the differential bus. The
ADM488A/ADM489A operate from a single 5 V ± 10% power
supply. A thermal shutdown circuit prevents excessive power
dissipation caused by bus contention or by output shorting.
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.
RE
The receiver contains a fail-safe feature that results in a logic
high output state if the inputs are unconnected (floating).
RE
The ADM488A/ADM489A can transmit at data rates up to
250 kbps. Figure 20 shows a typical application for the
ADM488A/ADM489A, a full-duplex link where data transfers
at rates of up to 250 kbps. A terminating resistor is shown at
both ends of the link. This termination is not critical because

APPLICATIONS INFORMATION
DIFFERENTIAL DATA TRANSMISSION
CABLE AND DATA RATE
Differential data transmission reliably transmits data at high
rates over long distances and through noisy environments.
Differential transmission nullifies the effects of ground shifts
and noise signals, which appear as common-mode voltages on
the line. Two main standards that specify the electrical characteristics of transceivers used in differential data transmission are
approved by the EIA.
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 generated
by the current flowing through each wire, thereby reducing the
effective inductance of the pair.
The RS-422 standard specifies data rates up to 10 Mbps and line
lengths up to 4000 ft. A single driver can drive a transmission
line with up to 10 receivers.
To cater to true multipoint communications, the RS-485 standard was defined to meet or exceed the requirements of RS-422.
It also allows 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 the
RS-422 and RS-485 is that the RS-485 drivers can be disabled,
thereby allowing up to 32 receivers 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.
The ADM488A/ADM489A are designed for bidirectional data
communications on multipoint transmission lines. A typical
application with a multipoint transmission network is illustrated
in Figure 22. An RS-485 transmission line can have up to 32
transceivers on the bus. Only one driver can transmit at a particular time, but multiple receivers can be simultaneously enabled.
As with any transmission line, it is important to minimize reflections. This can be achieved by terminating the extreme ends of the
line using resistors equal to the characteristic impedance of the
line. Keep stub lengths of the main line as short as possible. A
properly terminated transmission line appears purely resistive
to the driver.
