ISL32372EFBZ

Overview

The ISL32372EFBZ is a half-duplex RS-485 transceiver manufactured by Renesas Electronics. It operates within a supply voltage range of 3.0 V to 5.5 V and supports data rates up to 10 Mbps. The device features ±15 kV ESD protection on the bus pins and includes fail-safe circuitry to ensure a high logic state when the bus is idle. It is housed in an 8-lead SOIC package.

Feature Summary

• Integrated ±15 kV electrostatic discharge (ESD) protection on differential I/O lines
• Fail-safe receiver design maintains a high output during no-input or open-bus conditions
• Supports standard RS-485 communication protocols with half-duplex operation

Applications

• Industrial automation control systems
• Building automation networks
• Data acquisition systems

Procurement Notes

Verify the specific suffix 'EFBZ' against official Renesas documentation to confirm the exact package type, tape-and-reel quantity, and RoHS compliance status. Ensure the selected variant matches the required operating temperature range for the target application environment before finalizing procurement orders.

Selection Notes

Select this component for applications requiring robust ESD protection and reliable performance in noisy industrial environments. It serves as a suitable replacement for legacy Intersil parts within the RS-485 ecosystem. Confirm that the 10 Mbps data rate meets system requirements and that the 3.0 V minimum supply voltage aligns with the host controller's logic levels.

Part Context

This component belongs to the ISL3237x series of RS-485 transceivers. Originally developed by Intersil, the product line was integrated into Renesas Electronics following their acquisition. The series is designed for general-purpose serial communication where moderate speed and high noise immunity are prioritized over ultra-high-speed data transfer capabilities.

Replacement Considerations

Direct pin-compatible substitutes include the ISL32371EFBZ and ISL32373EFBZ from the same manufacturer family. Verify that the alternative part number shares the identical 8-lead SOIC footprint and electrical characteristics before implementation.
