Renesas Electronics Corporation Fault Protected, Extended Common Mode Range, RS-485/RS-422 Transceivers with 16.5kV ESD ISL32478EIBZ

The ISL32470E, ISL32472E, ISL32475E, ISL32478E are fault-protected, extended common mode range differential transceivers that exceed the RS-485 and RS-422 standards for balanced communication. The RS-485 bus pins (driver outputs and receiver inputs) are fault protected against overvoltages up to ±60V and are protected against ±16.5kV ESD strikes without latch-up. Additionally, these transceivers operate in environments with common mode voltages up to ±15V (exceeds the RS-485 requirement), making this fault-protected RS-485 family one of the more robust on the market.brbr Transmitters (Tx) deliver an exceptional 2.5V (typical) differential output voltage into the RS-485 specified 54? load. This yields better noise immunity than standard RS-485 ICs or allows up to six 120? terminations in star topologies.brbr 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 feature high drive levels; typically, 15mA @ VsubOL/sub = 1V (to ease the design of opto-coupled isolated interfaces).brbr Half duplex (Rx inputs and Tx outputs multiplexed together) and full duplex pinouts are available. See Table 1 on page 2 for key features and configurations by device number.brbr For a fault-protected RS-485 transceiver with a ±25V extended common mode range, please see the ISL32490E and ISL32483E data sheets.
