±±15k EꢀDꢁ-rotected, Isolated, 3.3k  
Rꢀꢁ481/Rꢀꢁ422 Data Interfaces  
General Description  
____________________________Features  
The MAX3480EA/MAX3480EB are electrically isolated  
RS-485/RS-422 data-communications interfaces. The  
RS-485/RS-422 I/O pins are protected against ±±5ꢀk  
electrostatic discharge (ESD) shocꢀs, without latchup.  
Transceivers, optocouplers, and a transformer are all  
included in one low-cost, 28-pin DIP pacꢀage. A single  
+3.3k supply on the logic side powers both sides of the  
interface.  
Isolated Data Interface Guaranteed to 1260V  
RMS  
(1min)  
15kV ESD Protection for I/O Pins  
Slew-Rate-Limited Data Transmission (160kbps for  
MAX3480EB)  
High-Speed, Isolated, 2.5Mbps RS-485 Interface  
(MAX3480EA)  
The MAX3480EB features reduced-slew-rate drivers  
that minimize EMI and reduce reflections caused by  
improperly terminated cables, allowing error-free data  
transmission at data rates up to ±60ꢀbps. The  
MAX3480EA’s driver slew rate is not limited, allowing  
transmission rates up to 2.5Mbps.  
Single +3.3V Supply  
Current Limiting and Thermal Shutdown for  
Driver Overload Protection  
Standard 28-Pin DIP Package  
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 the input  
is open circuit.  
Allows Up to 128 Transceivers on the Bus  
The MAX3480EA/MAX3480EB are guaranteed to with-  
stand ±260k  
(±min) or ±520k  
(±s). Their isolated  
RMS  
RMS  
-in Configuration  
inputs and outputs meet RS-485/RS-422 specifications.
