General Description  
__Next Generation Device Features  
o For Fault-Tolerant Applications  
The MAX481, MAX483, MAX485, MAX487–MAX491, and  
MAX1487 are low-power transceivers for RS-485 and RS-  
422 communication. Each part contains one driver and one  
receiver. The MAX483, MAX487, MAX488, and MAX489  
feature reduced slew-rate drivers that minimize EMI and  
reduce reflections caused by improperly terminated cables,  
thus allowing error-free data transmission up to 250kbps.  
The driver slew rates of the MAX481, MAX485, MAX490,  
MAX491, and MAX1487 are not limited, allowing them to  
transmit up to 2.5Mbps.

Transceiver in a ꢃOT23 ꢁacꢆage  
These transceivers draw between 120µA and 500µA of  
supply current when unloaded or fully loaded with disabled  
drivers. Additionally, the MAX481, MAX483, and MAX487  
have a low-current shutdown mode in which they consume  
only 0.1µA. All parts operate from a single 5V supply.

ꢃOT23d Rꢃ-4±51Rꢃ-422 Transmitters  
Drivers are short-circuit current limited and are protected  
against excessive power dissipation by thermal shutdown  
circuitry that places the driver outputs into a high-imped-  
ance state. The receiver input has a fail-safe feature that  
guarantees a logic-high output if the input is open circuit.  
o For Multiple Transceiver Applications

+3.3ꢀd Quaꢂ Rꢃ-422 Transmitters  
The MAX487 and MAX1487 feature quarter-unit-load  
receiver input impedance, allowing up to 128 MAX487/  
MAX1487 transceivers on the bus. Full-duplex communi-  
cations are obtained using the MAX488–MAX491, while  
the MAX481, MAX483, MAX485, MAX487, and MAX1487  
are designed for half-duplex applications.
