ISL32173EIVZ

Overview

The ISL32173EIVZ 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-TSSOP package (0.173 inch / 4.40mm width) and is rated for an extended industrial operating temperature range from -40°C to 125°C. The component complies with RoHS3 standards.

Feature Summary

• Supports high-speed data transmission up to 80Mbps on RS-422 and RS-485 networks.
• Provides robust noise rejection through 30mV receiver hysteresis.
• Operates reliably across the full industrial temperature range of -40°C to 125°C.

Applications

• Industrial control systems requiring reliable serial communication.
• Building automation and management networks.
• Data acquisition systems in harsh electrical environments.

Procurement Notes

Verify the specific suffix 'VZ' against official Renesas documentation to confirm the 16-TSSOP package and 125°C temperature rating, as these parameters define the component's environmental limits. Confirm current availability status, as this part number may be subject to discontinuation notices or production changes documented in public PCNs. Ensure compliance with required RoHS3 specifications for the target assembly process.

Selection Notes

Select this component when a quad receiver solution is required without integrated drivers for RS-422/RS-485 applications. The 16-TSSOP package is suitable for surface-mount designs with space constraints. Verify that the system power supply remains within the 3V to 5.5V range and that the 80Mbps data rate meets the network requirements. Consider the 125°C junction temperature capability for high-thermal environments.

Part Context

The ISL32173EIVZ belongs to the ISL32x73E family of interface ICs from Renesas. This family focuses on providing robust, low-power receivers for differential bus communications. The 'E' suffix typically denotes enhanced features such as higher speed or improved ESD protection compared to earlier generations. The 'VZ' suffix specifically identifies the TSSOP package variant within this product line.
