Description

The 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 VOL = 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.
