The ISL31490E, ISL31491E, ISL31492E, ISL31493E,

Features

ISL31495E, ISL31496E, ISL31498E are fault protected, 5V

• Fault protected RS-485 bus pins . . . . . . . . . . . . . . up to ±60V

powered, 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

protected against faults up to ±60V. 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 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

• 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

Transmitters 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

• Pb-free (RoHS compliant)

Receiver (Rx) inputs feature a “Full Fail-safe” design, which

ensures a logic high Rx output if Rx inputs are floating, shorted,

or on a terminated but undriven (idle) bus. Rx outputs have high

drive levels - typically 15mA at V = 1V (for opto-coupled,

isolated applications).

Applications

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.

• Utility meters/automated meter reading systems

• High node count systems

• PROFIBUS™ and field bus networks, and factory automation

• Security camera networks

For fault protected or wide common mode range devices with

cable invert (polarity reversal) please see the ISL32485E

datasheet.

• Building lighting and environmental control systems

• Industrial/process control networks
