ISL32173EFVZ-T

Overview

The ISL32173EFVZ-T is a quad receiver integrated circuit designed for RS-485 and RS-422 communication protocols. Manufactured by Renesas Electronics Corporation, this component operates within a supply voltage range of 3.0 V to 5.5 V. It supports data transmission rates up to 80 Mbps and features robust electrostatic discharge (ESD) protection rated at ±16.5 kV according to the Human Body Model. The device is housed in a 16-lead Thin Shrink Small Outline Package (TSSOP) with a width of 4.40 mm. It is specified for industrial temperature ranges extending from -40°C to +125°C.

Feature Summary

• Provides four independent receivers compliant with RS-485 and RS-422 standards
• Features high-level ESD protection capable of withstanding ±16.5 kV human body model discharges
• Supports high-speed data transmission with a maximum rate of 80 Mbps
• Operates reliably across an extended industrial temperature range of -40°C to +125°C

Applications

• Industrial control systems requiring robust serial communication interfaces
• Telecommunications equipment utilizing RS-485 or RS-422 bus architectures
• Building automation networks needing reliable long-distance data transfer

Procurement Notes

Verify the specific suffix 'EFVZ-T' to confirm the tape-and-reel packaging format and lead-free RoHS compliance status. Confirm that the procurement channel sources directly from authorized distributors to ensure authenticity, as counterfeit interface ICs are prevalent. Check current lifecycle status, as older Intersil-derived part numbers may have transitioned through multiple obsolescence notices or production changes under Renesas ownership.

Selection Notes

Select this component when a design requires only receiving capabilities rather than full transceiver functionality. Ensure the system voltage aligns with the 3.0 V to 5.5 V operating range. Verify that the PCB layout accommodates the 16-TSSOP package dimensions. Consider the 80 Mbps speed requirement against the cable length and noise environment to determine if lower-speed, higher-noise-immunity alternatives are more suitable for the specific application constraints.

Part Context

This part belongs to the ISL3217xE family of quad receivers originally developed by Intersil Corporation before its acquisition by Renesas Electronics. The series is characterized by high ESD tolerance and compatibility with standard RS-485/RS-422 signaling. The 'E' suffix typically denotes an extended industrial temperature grade, while 'FVZ' indicates the specific TSSOP package and lead-free composition.

Replacement Considerations

Direct pin-compatible replacements within the same family include ISL32173EFBZ and ISL32173EWUZ, differing primarily in package type. Cross-manufacturer equivalents should be evaluated based on matching ESD ratings, data rate specifications, and supply voltage ranges to ensure functional parity without redesigning the host circuit.
