ISL32173EFBZ

Overview

The ISL32173EFBZ is a quad receiver integrated circuit designed for RS-485 and RS-422 communication interfaces. 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 Mb/s and features ±16.5 kV electrostatic discharge (ESD) protection on the bus pins. The device is housed in a 16-lead SOIC narrow package with a maximum operating temperature of 125°C. It draws a typical quiescent current of 800 µA and includes a 30 mV receiver hysteresis to ensure noise immunity.

Feature Summary

• Provides four independent receivers for high-speed serial data acquisition
• Incorporates robust ±16.5 kV ESD protection for harsh industrial environments
• Features 30 mV hysteresis to improve signal integrity and noise rejection

Applications

• Industrial control systems requiring reliable RS-485/RS-422 connectivity
• Telecommunications equipment utilizing high-speed data reception
• Building automation networks with extended ESD protection needs

Procurement Notes

Verify the specific suffix 'FBZ' against the manufacturer's official datasheet to confirm the exact package type and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Check for end-of-life notices or alternative recommendations from Renesas, as discontinuation may affect long-term availability.

Selection Notes

Select this component when a quad receiver configuration is required without integrated drivers. Ensure the system design accommodates the 3.0 V to 5.5 V supply range. Verify that the 80 Mb/s data rate meets the application's throughput requirements. Consider the 16-SOIC package dimensions for PCB layout constraints.

Part Context

This part belongs to the ISL3217xE family of interface ICs, which are engineered for high-speed, high-reliability communication. The family typically includes variants with different numbers of drivers and receivers, such as transceivers or pure driver configurations. The 'E' designation often indicates enhanced ESD protection capabilities compared to standard industry levels.

Replacement Considerations

Consult the official datasheet for pin-compatible alternatives within the ISL3217x series. Verify if other manufacturers offer electrically equivalent quad receivers with similar ESD ratings and data speeds.
