ISL15100IRZ-T7

Overview

The ISL15100IRZ-T7 is a high-speed, low-power RS-422/RS-485 transceiver manufactured by Renesas Electronics Corporation. It integrates three receivers and one driver within a compact 32-pin QFN package (5x6 mm). The device operates on a single 5V supply with a typical quiescent current of 110 mA. It supports data rates up to 10 Mbps and functions reliably across an extended industrial temperature range from -40°C to +85°C. The component features ESD protection rated at ±15 kV HBM and includes fail-safe circuitry to ensure a high logic state when inputs are open.

Feature Summary

• Integrated triple differential receiver and single differential driver for multi-drop communication
• Robust electrostatic discharge protection meeting ±15 kV Human Body Model standards
• Fail-safe design guarantees a defined high output state during input disconnection

Applications

• Industrial automation control networks
• Building management systems
• Multi-drop serial communication buses

Procurement Notes

Verify the specific suffix T7 indicates tape and reel packaging upon ordering. Confirm RoHS compliance status as the component may be subject to End-of-Life notices. Ensure the 32-VFQFN exposed pad thermal requirements are addressed in the PCB layout design prior to procurement.

Selection Notes

Select this component when a single IC must handle multiple receive lines alongside a transmit line in space-constrained designs. Verify that the 5V operating voltage aligns with the system power rails. Consider the 32-pin footprint dimensions against available board real estate compared to smaller packages.

Part Context

This part belongs to the ISL151xx series of high-speed transceivers designed for robust serial communication. It serves as a bridge between microcontroller UARTs and balanced transmission lines. The device replaces older discrete solutions by integrating protection and signal conditioning into a single surface-mount package.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with direct pin-to-pin replacements through official Renesas cross-reference tools before substitution.
