General Description  
Features  
The MAX3430 fault-protected RS-485 transceiver features  
80V protection from overvoltage signal faults on commu-  
nication bus lines. Each device contains one driver and  
one receiver, and the output pins can withstand faults,  
with respect to ground, of up to 80V. Even if the faults  
occur when the transceiver is active, shut down, or pow-  
ered off, the device will not be damaged. The MAX3430  
operates from a 3.3V supply and features a slew-rate-lim-  
ited driver that minimizes EMI and reduces reflections  
caused by improperly terminated cables, allowing error-  
free data transmission at data rates up to 250kbps. The  
MAX3430 has a 1/4-unit-load receiver input impedance  
allowing up to 128 transceivers on a single bus and fea-  
tures fail-safe circuitry, which guarantees a logic-high  
receiver output when the receiver inputs are open.

Hot-swap circuitry eliminates false transitions on the  
data cable during circuit initialization or connection to a  
live backplane. Short-circuit current limiting and ther-  
mal-shutdown circuitry protect the driver against exces-  
sive power dissipation.  
Ordering Information  
The MAX3430 is available in 8-pin SO and 8-pin PDIP  
packages, and is specified over commercial and indus-  
trial temperature ranges.
