♦ ESD Protection: ±15kV—Human Body Model  
The MAX481E, MAX483E, MAX485E, MAX487E–MAX491E,  
and MAX1487E are low-power transceivers for RS-485 and  
RS-422 communications in harsh environments. Each driver  
output and receiver input is protected against ±15kV electro-  
static discharge (ESD) shocks, without latchup. These parts  
c onta in one d rive r a nd one re c e ive r. The MAX483E,  
MAX487E, MAX488E, and MAX489E 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  
MAX481E, MAX485E, MAX490E, MAX491E, and MAX1487E  
are not limited, allowing them to transmit up to 2.5Mbps.  
♦ Slew-Rate Limited for Error-Free Data  
Transmission (MAX483E/487E/488E/489E)  
♦ Low Quiescent Current:  
120µA (MAX483E/487E/488E/489E)  
230µA (MAX1487E)  
300µA (MAX481E/485E/490E/491E)  
♦ -7V to +12V Common-Mode Input Voltage Range  
♦ Three-State Outputs  
♦ 30ns Propagation Delays, 5ns Skew  
(MAX481E/485E/490E/491E/1487E)  
These transceivers draw as little as 120µA supply current  
when unloaded or when fully loaded with disabled drivers  
(s e e Se le c tion Ta b le ). Ad d itiona lly, the MAX481E,  
MAX483E, and MAX487E have a low-current shutdown  
mode in which they consume only 0.5µA. All parts operate  
from a single +5V supply.  
♦ Full-Duplex and Half-Duplex Versions Available  
♦ Allows up to 128 Transceivers on the Bus  
(MAX487E/MAX1487E)  
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 guaran-  
tees a logic-high output if the input is open circuit.  
♦ Current Limiting and Thermal Shutdown for  
Driver Overload Protection  
The MAX487E and MAX1487E feature quarter-unit-load  
receiver input impedance, allowing up to 128 transceivers  
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 sen-  
sitive se e the p in- a nd func tion-c ompa tible MAX481,  
MAX483, MAX485, MAX487–MAX491, and MAX1487.
