DATASHEET  
ISL32483E, ISL32485E  
Fault Protected, Extended CMR, RS-485/RS-422 Transceivers with Cable Invert  
and ±16.5kV ESD  
FN7785  
Rev.4.00  
Feb 15, 2019  
The ISL32483E and ISL32485E (ISL3248xE) are fault protected,  
Features  
5V powered differential transceivers that exceed the RS-485 and  
• Fault protected RS-485 bus pins . . . . . . . . . . . . . . up to ±60V  
RS-422 standards for balanced communication. The RS-485  
transceiver pins (driver outputs and receiver inputs) are fault  
protected up to ±60V and are protected against ±16.5kV ESD  
strikes without latch-up. Additionally, the extended common-  
mode range allows these transceivers to operate in environments  
with common-mode voltages up to ±25V (>2X the RS-485  
requirement), making this fault-protected RS-485 family one of  
the most robust on the market.  
• Extended common-mode range. . . . . . . . . . . . . . . . . . . . ±25V  
more than twice the range required for RS-485  
• ±16.5kV HBM ESD protection on RS-485 bus pins  
• Cable invert pins corrects for reversed cable connections  
while maintaining Rx full fail-safe functionality  
• Full fail-safe (open, short, terminated) RS-485 receivers  
• 1/4 Unit Load (UL) for up to 128 devices on the bus  
The transmitters (Tx) deliver an exceptional 2.5V (typical)  
differential output voltage into the RS-485 specified 54Ω load.  
This yields better noise immunity than standard RS-485 ICs or  
allows up to six 120Ω terminations in star network topologies.  
• High Rx I for opto-couplers in isolated designs  
OL  
• Hot plug circuitry: Tx and Rx outputs remain three-state  
during power-up/power-down  
The receiver (Rx) inputs feature a full fail-safe design that  
ensures a logic high Rx output if the Rx inputs are floating,  
shorted, or on a terminated but undriven (idle) bus.  
• Slew rate limited RS-485 data rate . . . . . . . . . . . . . . . 1Mbps  
• Low quiescent supply current. . . . . . . . . . . . . . . . . . . . 2.3mA  
• Ultra low shutdown supply current. . . . . . . . . . . . . . . . . . 10µA  
The ISL32483E and ISL32485E include cable invert functions  
that reverse the polarity of the Rx and/or Tx bus pins if the  
cable is misconnected. Unlike competing devices, the Rx full  
fail-safe operation is maintained even when the Rx input  
polarity is switched.  
Applications  
• Utility meters/automated meter reading systems  
• High node count RS-485 systems  
For fault protected RS-485 transceivers without the cable  
invert function, see the ISL32470E and ISL32490E  
datasheets.  
• PROFIBUS™ and RS-485 based field bus networks and  
factory automation  
• Security camera networks  
• Building lighting and environmental control systems  
• Industrial/process control networks
