20A / 1.8-Unit-Load / Slew-Rate-Limited RS-485 Transceivers
_______________General DescriptionThe 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.

ABSOLUTE MAXIMUM RATINGSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 3:The MAX1482/MAX1483 are put into shutdown by bringing–R—E–high and DE low. If the inputs are in this state for less
than 50ns, the parts are guaranteed not to enter shutdown. If the inputs are in this state for at least 600ns, the parts are
guaranteed to have entered shutdown. See Low-Power Shutdown Modesection.
