ISL32172EIBZ

Overview

The ISL32172EIBZ is a quad receiver integrated circuit manufactured by Renesas Electronics Corporation, designed for RS-422 and RS-485 communication protocols. It features four receivers with zero drivers, operating within a supply voltage range of 3V to 5.5V. The device supports data rates up to 80Mbps and includes a receiver hysteresis of 30mV to improve noise immunity. It is housed in a 16-SOIC package (0.154" width) and is rated for an industrial operating temperature range of -40°C to +85°C. The component complies with RoHS3 standards and has a Moisture Sensitivity Level (MSL) of 3.

Feature Summary

• Provides four differential receivers optimized for RS-422 and RS-485 bus networks.
• Incorporates 30mV input hysteresis to enhance signal integrity in noisy environments.
• Supports high-speed data transmission with a maximum rate of 80Mbps.
• Operates reliably across the full industrial temperature range from -40°C to +85°C.

Applications

• Industrial control systems requiring robust serial communication.
• Building automation and security network interfaces.
• Data acquisition systems utilizing RS-485 multi-drop configurations.

Procurement Notes

Verify the specific suffix 'EIBZ' to confirm the 16-SOIC package and lead-free status. Confirm that the required data rate and voltage levels align with the 80Mbps and 3V-5.5V specifications. Ensure the design accommodates the MSL 3 rating for proper storage and handling procedures during assembly.

Selection Notes

Select this component when a standalone quad receiver is needed for RS-422/RS-485 applications without integrated driver functionality. Compare against the ISL32173EIBZ if transceiver capabilities are required instead of receivers only. Verify that the 16-SOIC footprint fits the PCB layout constraints and that the 30mV hysteresis meets the noise margin requirements of the specific bus environment.

Part Context

This part belongs to the ISL32x73E family of interface ICs from Renesas, which also includes variants like the ISL32173EIBZ. These devices are engineered for reliable half-duplex and full-duplex communication in industrial settings. The EIBZ designation specifically denotes the SOIC package variant within this series.

Replacement Considerations

The ISL32173EIBZ is a listed alternative but functions as a transceiver (1 driver/4 receivers) rather than a pure receiver. Verify if the additional driver capability is acceptable or if it introduces unnecessary complexity. No other direct pin-to-pin substitutes are confirmed in the provided documentation.
