RENISL32470EIBZ-T
Overview
The ISL32470EIBZ-T is a high-reliability, full-duplex RS-485/RS-422 transceiver designed for operation in harsh industrial environments. It features an exceptionally wide common-mode input range of plus or minus 60V, providing robust protection against large ground potential differences and transient surges. Operating from a 5V supply, this 14-SOIC device supports data rates up to 250kbps while maintaining low power consumption.
Why Choose This Part
The primary advantage is the plus or minus 60V fault protection on the bus pins, which eliminates the need for external surge protection in many applications. It offers a low shutdown current of 10uA and a typical operating current of 2.3mA, making it efficient for remote nodes. The 25mV receiver hysteresis improves noise immunity in environments with high electromagnetic interference.

Key Specifications
Getting Started
To evaluate this part, design a 14-SOIC breakout board or integrate it into a prototype using a 5V supply and standard logic-level UART signals. Ensure a 0.1uF decoupling capacitor is placed close to the VDD pin and terminate the RS-485 bus with 120-ohm resistors at both ends of the cable. No specialized firmware is required beyond standard UART configuration at 250kbps or lower.
