Data Sheet  
August 28, 2006  
FN6307.2  
±15kV ESD Protected, 3.3V, Full Fail-safe,  
Low Power, High Speed or Slew Rate  
Limited, RS-485/RS-422 Transceivers  
Features  
• IEC61000 ESD Protection on RS-485 I/O Pins . . . . . ±15kV  
- Class 3 ESD Level on all Other Pins . . . . . . >7kV HBM  
The Intersil ISL317XE are ±15kV IEC61000 ESD Protected,  
3.3V powered, single transceivers that meet both the  
RS-485 and RS-422 standards for balanced communication.  
These devices have very low bus currents (+125μA/-100μA),  
so they present a true “1/8 unit load” to the RS-485 bus. This  
allows up to 256 transceivers on the network without violating  
the RS-485 specification’s 32 unit load maximum, and without  
using repeaters. For example, in a remote utility meter reading  
system, individual meter readings are routed to a concentrator  
via an RS-485 network, so the high allowed node count  
minimizes the number of repeaters required.  
• Pb-Free Plus Anneal Available (RoHS Compliant)  
• Full Fail-safe (Open, Short, Terminated/Floating)  
Receivers  
• Hot Plug - Tx and Rx Outputs Remain Three-state During  
Power-up  
• True 1/8 Unit Load Allows up to 256 Devices on the Bus  
• Single 3.3V Supply  
• High Data Rates. . . . . . . . . . . . . . . . . . . . . . up to 20Mbps  
• Low Quiescent Supply Current . . . . . . . . . . .800μA (Max)  
Receiver (Rx) inputs feature a “Full Fail-Safe” design, which  
ensures a logic high Rx output if Rx inputs are floating,  
shorted, or terminated but undriven.  
- Ultra Low Shutdown Supply Current . . . . . . . . . . .10nA  
• -7V to +12V Common Mode Input/Output Voltage Range  
• Half and Full Duplex Pinouts  
Hot Plug circuitry ensures that the Tx and Rx outputs remain  
in a high impedance state while the power supply stabilizes.  
• Three State Rx and Tx Outputs Available  
The ISL3170E through ISL3175E utilize slew rate limited  
drivers which reduce EMI, and minimize reflections from  
improperly terminated transmission lines, or unterminated  
stubs in multidrop and multipoint applications. Slew rate limited  
versions also include receiver input filtering to enhance noise  
immunity in the presence of slow input signals.  
• Current Limiting and Thermal Shutdown for driver  
Overload Protection  
• Tiny MSOP Packages Consume 50% Less Board Space  
Applications  
• Automated Utility Meter Reading Systems  
• High Node Count Systems  
The ISL3170E, ISL3171E, ISL3173E, ISL3174E, ISL3176E,  
ISL3177E are configured for full duplex (separate Rx input  
and Tx output pins) applications. The half duplex versions  
multiplex the Rx inputs and Tx outputs to allow transceivers  
with output disable functions in 8 lead packages.  
• Field Bus Networks  
• Security Camera Networks  
• Building Environmental Control/ Lighting Systems  
• Industrial/Process Control Networks
