ISL32173EFVZ

Overview

The ISL32173EFVZ is a quad receiver integrated circuit designed for RS-422 and RS-485 communication protocols. Manufactured by Renesas Electronics Corporation, this component operates within a supply voltage range of 3V to 5.5V. It supports data transmission rates up to 80Mbps and features a receiver hysteresis of 30mV to enhance noise immunity. The device is housed in a 16-TSSOP package with a width of 4.40mm and is rated for an extended operating temperature range from -40°C to 125°C. This specific part number indicates the tube packaging variant.

Feature Summary

• Quad receiver configuration supporting RS-422 and RS-485 standards
• High-speed data capability up to 80Mbps
• Extended industrial temperature rating up to 125°C
• Integrated 30mV hysteresis for improved signal integrity

Applications

• Industrial control systems requiring robust differential signaling
• Multi-drop communication networks utilizing RS-485 bus architectures
• Data acquisition systems operating in high-noise environments

Procurement Notes

Verify current availability status as the ISL32173EFVZ has been reported as obsolete or end-of-life in certain distributor records. Confirm the specific suffix 'FVZ' corresponds to the TSSOP tube packaging variant rather than tape-and-reel or alternative packages like SOIC. Cross-reference the manufacturer's latest product change notices to ensure compliance with RoHS3 specifications and check for any recommended replacement components if active sourcing is required.

Selection Notes

Select this component when a standalone quad receiver is needed for RS-422/RS-485 applications requiring high data rates and wide temperature tolerance. Ensure the design utilizes only receivers without integrated drivers, as this part lacks transmitter functionality. Verify that the system power supply remains within the 3V to 5.5V range and that the PCB layout accommodates the 16-TSSOP footprint with appropriate thermal management for the 125°C maximum junction temperature.

Part Context

The ISL32173E series belongs to Renesas' portfolio of high-speed RS-422 and RS-485 interface devices. The EFVZ suffix specifically denotes the 16-TSSOP package variant with an extended temperature range. Other variants in the family include the EIBZ (SOIC package) and different temperature grades. This component is part of the broader ISL32x73E family, which shares similar electrical characteristics but differs in packaging and operational limits.

Replacement Considerations

Publicly confirmed substitute part numbers are not explicitly listed in the provided source material. Designers should consult the manufacturer's official documentation for direct pin-to-pin replacements or functional equivalents within the ISL32x73E family, such as the ISL32173EIBZ for SOIC packaging, while verifying package compatibility and temperature ratings.
