ISL32430E, ISL32432E, ISL32433E, ISL32435E, ISL32437E  
±40V Fault Protected, 3.3V to 5V, ±15V Common-Mode Range, RS-485/RS-422  
Transceivers With Cable Invert and ±15kV ESD  
FN7920  
Rev.1.00  
Feb 15, 2019  
The ISL32430E, ISL32432E, ISL32433E, ISL32435E, and  
Features  
ISL32437E are 3.3V to 5V powered, fault protected, extended  
• Fault protected RS-485 bus pins . . . . . . . . . . . . . . up to ±40V  
common-mode range differential transceivers for balanced  
communication. The RS-485 bus pins, driver outputs and  
receiver inputs, are protected against overvoltages up to ±40V  
and against ±15kV ESD strikes. Additionally, these transceivers  
operate in environments with common-mode voltages up to  
±15V (exceeds the RS-485 requirement), making this RS-485  
family one of the most robust on the market.  
• Extended common-mode range. . . . . . . . . . . . . . . . . . . . ±15V  
larger than required for RS-485  
• ±15kV HBM ESD protection on RS-485 bus pins  
• Wide supply range . . . . . . . . . . . . . . . . . . . . . . . . . . 3V to 5.5V  
• Cable invert pin corrects for reversed cable connections  
while maintaining Rx full fail-safe functionality (ISL32437E  
only)  
The transmitters are RS-485 compliant with V ≥ 4.5V and  
CC  
deliver a 1.1V differential output voltage into the RS-485  
specified 54Ω load even with V = 3V.  
• 1/4 Unit load for up to 128 devices on the bus  
CC  
• High transient overvoltage tolerance. . . . . . . . . . . . . . . . ±60V  
• Full fail-safe (open, short, terminated) RS-485 receivers  
• Choice of RS-485 data rates . . . . . . . . . . . . . 250kbps or 1Mbps  
• Low quiescent supply current. . . . . . . . . . . . . . . . . . . . 2.1mA  
• Ultra low shutdown supply current. . . . . . . . . . . . . . . . . . 10µA  
• Pb-free (RoHS compliant)  
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. The Rx full  
fail-safe operation is maintained even when the Rx input polarity  
is switched (cable invert function on ISL32437E).  
The ISL32437E includes a cable invert function that reverses  
the polarity of the Rx and Tx bus pins if the cable is  
misconnected during installation.  
Applications  
• Utility meters/automated meter reading systems  
See Table 1 on page 4 for key features and configurations by  
device number.  
• Air conditioning systems
