MAX3483/MAX3485/MAX3486/  
MAX3488/MAX3490/MAX3491  
3.3V-Powered, 10Mbps and Slew-Rate-Limited  
True RS-485/RS-422 Transceivers  
_______________General Description  
____________________________Features  
The MAX3483, MAX3485, MAX3486, MAX3488,  
MAX3490, and MAX3491 are 3.3V, low-power trans-  
ceivers for RS-485 and RS-422 communication. Each  
part contains one driver and one receiver. The  
MAX3483 and MAX3488 feature slew-rate-limited dri-  
vers that minimize EMI and reduce reflections caused  
by improperly terminated cables, allowing error-free  
data transmission at data rates up to 250kbps. The par-  
tially slew-rate-limited MAX3486 transmits up to  
2.5Mbps. The MAX3485, MAX3490, and MAX3491  
transmit at up to 10Mbps.  
Operate from a Single 3.3V Supply—  
No Charge Pump!  
Interoperable with +5V Logic  
8ns Max Skew (MAX3485/MAX3490/MAX3491)  
Slew-Rate Limited for Errorless Data Transmission  
(MAX3483/MAX3488)  
2nA Low-Current Shutdown Mode  
(MAX3483/MAX3485/MAX3486/MAX3491)  
-7V to +12V Common-Mode Input Voltage Range  
Allows up to 32 Transceivers on the Bus  
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 both  
inputs are open circuit.  
Full-Duplex and Half-Duplex Versions Available  
Industry Standard 75176 Pinout  
(MAX3483/MAX3485/MAX3486)  
The MAX3488, MAX3490, and MAX3491 feature full-  
duplex communication, while the MAX3483, MAX3485,  
and MAX3486 are designed for half-duplex communi-  
cation.  
Current-Limiting and Thermal Shutdown for  
Driver Overload Protection
