_______________General Description
The MAX1482 and MAX1483 are low-power trans-
ceivers for RS-485 and RS-422 communication. Both
feature slew-rate-limited drivers that minimize EMI and
reduce reflections caused by improperly terminated
cables. Data rates are guaranteed up to 250kbps.
The MAX1482/MAX1483 draw only 20µA of supply cur-
rent. Additionally, they have a low-current shutdown
mode that consumes only 0.1µA. Both parts operate
from a single +5V supply.
Drivers are short-circuit current limited and are protect-
ed against excessive power dissipation by thermal
shutdown circuitry that places the driver outputs into a
high-impedance state. The receiver input has a fail-safe
feature that guarantees a logic-high output if the input
is open circuit.
The MAX1482 is full duplex and the MAX1483 is half
duplex. Both parts have a 1⁄8-unit-load input impedance
that guarantees up to 256 transceivers on the bus.

Driver Output Enable. The driver outputs, A and B, (Y and Z for the MAX1482)
are enabled by bringing DE high. When DE is low, the driver outputs are high
impedance, and the devices can function as line receivers if RE is low. If RE is
high and DE is low, the parts will enter a low-power (0.1µA) shutdown state. If
the driver outputs are enabled, the devices function as line drivers.

MAX1482/MAX1483
__________Applications Information
The MAX1482/MAX1483 are low-power transceivers for
RS-485 and RS-422 communications. The MAX1482
and MAX1483 are specified for data rates of at least
250kbps. The MAX1482 is a full-duplex transceiver
while the MAX1483 is half duplex. When disabled, the
driver and receiver outputs are high impedance.
The 96kΩ, 1/8-unit-load receiver input impedance of the
MAX1482/MAX1483 allows up to 256 transceivers on a
bus, compared to the 1-unit load (12kΩinput imped-
ance) of standard RS-485 drivers (32 transceivers max-
imum). Any combination of MAX1482/MAX1483 and
other RS-485 transceivers with a total of 32 unit loads or
less can be put on the bus.
Reduced EMI and Reflections
The MAX1482/MAX1483 are slew-rate limited, minimiz-
ing EMI and reducing reflections caused by improperly
terminated cables. Figure 9 shows both the driver out-
put waveform of a MAX1482/MAX1483 transmitting a
125kHz signal and the Fourier analysis of that signal.
High-frequency harmonics have much lower ampli-
tudes, and the potential for EMI is significantly reduced.

Low-Power Shutdown Mode
A low-power shutdown mode is initiated by bringing RE
high and DE low. The devices will not shut down unless
both the driver and receiver are disabled. In shut-
down, the devices typically draw only 0.1µA of supply
current.
RE and DE may be driven simultaneously; the parts are
guaranteed not to enter shutdown if RE is high and DE
is low for less than 50ns. If the inputs are in this state for
at least 600ns, the parts are guaranteed to enter shut-
down.
For the receiver, the tZH and tZL enable times assume
the part was not in the low-power shutdown state. The
tZH(SHDN) and tZL(SHDN) enable times assume the
parts were shut down (see Electrical Characteristics).
It takes the receivers longer to become enabled from
the low-power shutdown state (tZH(SHDN), tZL(SHDN))
than from the operating mode (tZH, tZL). (The parts are
in operating mode if the RE , DE inputs equal a logical
0,1 or 1,1 or 0,0.)
Driver Output Protection
Excessive output current and power dissipation caused
by faults or by bus contention are prevented by two
mechanisms. A foldback current limit on the output
stage provides immediate protection against short cir-
cuits over the whole common-mode voltage range (see
Typical Operating Characteristics). In addition, a ther-
mal shutdown circuit forces the driver outputs into a
high-impedance state if the die temperature rises
excessively.
Propagation Delay
Digital encoding schemes depend on the driver and
receiver skew. Skew is defined as the difference
between the rising and falling propagation delay times.
Typical propagation delays are shown in Figures 11
and 12 using Figure 10’s test circuit.
The difference in receiver delay times, | tPLH - tPHL |, is
typically under 160ns.
The driver skew times are typically 160ns (800ns max).

Line Length vs. Data Rate
The RS-485/RS-422 standard covers line lengths up to
4000 feet. For line lengths greater than 4000 feet, see
Figure 16.
Figure 13 shows the system differential voltage for the
parts driving 4000 feet of 26AWG twisted-pair wire at
110kHz into 120Ωloads. Even after 4000 feet of cable,
the MAX1482/MAX1483 output shows virtually no dis-
tortion.
Typical Applications
The MAX1482/MAX1483 transceivers are designed for
bidirectional data communications on multipoint bus
transmission lines. Figures 14 and 15 show typical net-
work applications circuits. These parts can also be
used as line repeaters, with cable lengths longer than
4000 feet, as shown in Figure 16.
To minimize reflections, the line should be terminated at
both ends in its characteristic impedance, and stub
lengths off the main line should be kept as short as
possible (although the slew-rate-limited MAX1482 and
MAX1483 are more tolerant of imperfect termination
than standard RS-485 ICs).
Isolated RS-485
For isolated RS-485 applications, see the MAX253 and
MAX1480 data sheets.
