ISL31490E, ISL31491E, ISL31492E, ISL31493E,

ISL31495E, ISL31496E, ISL31498E

are fault protected, 5V

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.

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.

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).

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.

For fault protected or wide common mode range devices with

cable invert (polarity reversal) please see the

ISL32485E

datasheet.
