+5.0V, ±±0ꢀV ESD-Protected, Fail-Safe,  
Hot-Swap, RS-485/RS-422 Transceiver  
General Description  
Features  
The MAX14780E +5.0V, ±±0ꢀV ESD-protected, RS-485/  
RS-422 transceiver features one driver and one receiver.  
The device includes fail-safe circuitry, guaranteeing a  
logic-high receiver output when receiver inputs are open  
or shorted. The receiver outputs a logic-high if all trans-  
mitters on a terminated bus are disabled (high imped-  
ance). The MAX14780E includes a hot-swap capability  
to eliminate false transitions on the bus during power-up  
or hot insertion.  
S +5.0V Operation  
S Extended ESD Protection for RS-485/RS-422 I/O  
Pins ±±0ꢀV Human Body Model  
S True Fail-Safe Receiver While Maintaining EIA/  
TIA-485 Compatibility  
S Hot-Swap Input Structures on DE and RE  
S Enhanced Slew-Rate Limiting Facilitates Error-  
Free Data Transmission  
The MAX14780E features reduced slew-rate drivers that  
minimize EMI and reduce reflections caused by improp-  
erly terminated cables, allowing error-free data transmis-  
sion up to 500ꢀbps.  
S Low-Current Shutdown Mode  
S Allow Up to 256 Transceivers on the Bus  
S Available in Industry-Standard 8-Pin SO Pacꢀage  
The MAX14780E is ideal for half-duplex communications  
and it draws 1.2mA of supply current when unloaded  
or when fully loaded with the drivers disabled. The  
MAX14780E has a 1/8-unit load receiver input imped-  
ance, allowing up to 256 transceivers on the bus.  
The MAX14780E is available in an 8-pin SO pacꢀage.
