±60V Fault Protected, 5V, RS-485/RS-422 Transceivers with ±25V CMR and ESD Protection

Rev.6.00

The ISL32490E, ISL32492E, ISL32493E, ISL32495E,  
Features  
ISL32496E, and ISL32498E are fault protected, 5V powered,  
• Fault protected RS-485 bus pins . . . . . . . . . . . . . . up to ±60V  
differential transceivers that exceed the RS-485 and 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  
(CMR) 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 CMR . . . . . . . . . . ±25V (more than twice the range  
required for RS-485)  
• ±16.5kV HBM ESD protection on RS-485 bus pins  
• 1/4 unit load for up to 128 devices on the bus  
• High transient overvoltage tolerance. . . . . . . . . . . . . . . . ±80V  
• Full fail-safe (open, short, terminated) RS-485 receivers  
• High Rx I for opto-couplers in isolated designs  
OL  
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.  
• Hot plug circuitry; Tx and Rx outputs remain three-state  
during power-up/power-down  
• Choice of RS-485 data rates. . . . . . . . . . 250kbps to 15Mbps  
• Low quiescent supply current. . . . . . . . . . . . . . . . . . . . 2.3mA  
• Ultra low shutdown supply current. . . . . . . . . . . . . . . . . . 10µA  
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  
outputs have high drive levels; typically, 15mA at V = 1V (for  
opto-coupled, isolated applications).  
OL  
Applications  
• Utility meters/automated meter reading systems  
Half duplex (Rx inputs and Tx outputs multiplexed together)  
and full duplex pinouts are available. See Table 1 on page 3 for  
key features and configurations by device number.  
• High node count RS-485 systems  
• PROFIBUS and RS-485 based field bus networks, and factory  
automation  
For fault protected or wide common-mode range RS-485  
transceivers with cable invert (polarity reversal) pins, see the  
ISL32483E datasheet.  
• Security camera networks  
• Building lighting and environmental control systems  
• Industrial/process control networks
