General Description  
Next-Generation Device Features  
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 15ꢀk electro-static discharge ꢁESꢂD shocꢀs,  
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 250ꢀbps. 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 GuideD. 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 +5k supply.

ꢃOT23d Rꢃ-4±51Rꢃ-422 Transmitters  
ꢂrivers 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 ESꢂ sensitive see the pin-  
and function-compatible MAX481, MAX483, MAX485,  
MAX487–MAX491, and MAX1487.
