Description

The ISL32490E, ISL32492E, ISL32493E, ISL32495E, ISL32496E, and ISL32498E 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 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. 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. 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 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 RS-485 transceivers with cable invert (polarity reversal) pins, see the ISL32483E datasheet.
