Complete, Isolated RS-485/RS-422  
Data Interface  
_________________General Description  
____________________________Features  
ꢀ Isolated Data Interface, Typically to 1600V  
The MAX1480A/MAX1480B/MAX1480C/MAX1490A/  
MAX1490B are complete, electrically isolated, RS-485/  
RS-422 data-communications interface solutions in a  
hybrid microcircuit. Transceivers, optocouplers, and a  
transformer provide a complete interface in a standard  
DIP package. A single +5V supply on the logic side pow-  
ers both sides of the interface.  
RMS  
(1 minute)  
ꢀ Slew-Rate Limited for Errorless Data  
Transmission (MAX1480B/MAX1480C/MAX1490B)  
ꢀ High-Speed, Isolated, 2.5Mbps RS-485/RS-422  
Interface (MAX1480A/MAX1490A)  
ꢀ Full-Duplex Data Communication (MAX1490A/B)  
The MAX1480B/MAX1480C/MAX1490B feature reduced-  
slew-rate drivers that minimize EMI and reduce reflec-  
tions caused by improperly terminated cables, allowing  
error-free data transmission at data rates up to 250kbps.  
The MAX1480A/MAX1490A driver slew rate is not limited,  
allowing transmission rates up to 2.5Mbps. The  
MAX1480A/B/C are designed for half-duplex communi-  
cation, while the MAX1490A/B feature full-duplex com-  
munication.  
ꢀ -7V to +12V Common-Mode Input Voltage Range  
with Respect to Isolated Ground  
ꢀ Single +5V Supply  
ꢀ Current Limiting and Thermal Shutdown for  
Driver Overload Protection  
ꢀ Standard 0.6" DIP Package:  
28-Pin DIP (MAX1480A/B/C)  
24-Pin DIP (MAX1490A/B)  
Drivers are short-circuit current limited and protected  
against excessive power dissipation by thermal shut-  
down circuitry that places the driver outputs into a high-  
impedance state. The receiver input has a fail-safe  
feature that guarantees a known output (RO low for the  
MAX1480A/B/C, RO high for the MAX1490A/B/C) if the  
input is open circuit.
