The MAX481E, MAX483E, MAX485E, MAX487E–

MAX491E, and MAX1487E are low-power transceivers for

RS-485 and RS-422 communications in harsh environ-

ments. Each driver output and receiver input is protected

against ±15kV electro-static discharge (ESD) shocks,

without latchup. These parts contain one driver and one

receiver. The MAX483E, MAX487E, MAX488E, and

MAX489E feature reduced slew-rate drivers that minimize

EMI and reduce reflections caused by improperly termi-

nated cables, thus allowing error-free data transmission

up to 250kbps. The driver slew rates of the MAX481E,

MAX485E, MAX490E, MAX491E, and MAX1487E are not

limited, allowing them to transmit up to 2.5Mbps.

These transceivers draw as little as 120µA supply cur-

rent when unloaded or when fully loaded with disabled

drivers (see Selector Guide). Additionally, the MAX481E,

MAX483E, and MAX487E have a low-current shutdown

mode in which they consume only 0.5µA. All parts oper-

ate from a single +5V supply.

Drivers are short-circuit current limited, and are protected

against excessive power dissipation by thermal shutdown

circuitry that places their outputs into a high-impedance

state. The receiver input has a fail-safe feature that guar-

antees a logic-high output if the input is open circuit.

The MAX487E and MAX1487E feature quarter-unit-load

receiver input impedance, allowing up to 128 trans-

ceivers on the bus. The MAX488E–MAX491E are

designed for full-duplex communications, while the

MAX481E, MAX483E, MAX485E, MAX487E, and

MAX1487E are designed for half-duplex applications.

For applications that are not ESD sensitive see the pin-

and function-compatible MAX481, MAX483, MAX485,

MAX487–MAX491, and MAX1487.
