Renesas Electronics Corporation ±60V Fault Protected, 5V, RS-485/RS-422 Transceivers with ±25V CMR and ESD Protection ISL32493EIBZ-T

The ISL32490E, ISL32492E, ISL32493E, ISL32495E, ISL32496E, 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 (CNR) 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.
Transmitters (Tx) deliver an exceptional 2.5V (typical) differential output voltage into the RS-485 specified 54O load. This yields better noise immunity than standard RS-485 ICs, or allows up to six 120O terminations in star network topologies.
Receiver (Rx) inputs feature a “full fail-safe” design that 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_OL = 1V (for opto-coupled, isolated applications).
Half duplex (Rx inputs and Tx outputs multiplexed together) and full duplex pinouts are available. Refer to Table 1 on page 2 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, refer to the ISL32483E data sheet.
