ISL32179EIRZ-T

Overview

The ISL32179EIRZ-T is a quad RS-422 driver manufactured by Renesas Electronics Corporation, housed in a QFN-EP-24 surface-mount package. It operates on a supply voltage ranging from 3 V to 5.5 V with a maximum operating current of 800 uA. The component supports data rates up to 32 Mb/s and provides 15 kV ESD protection. It functions within an ambient temperature range of -40°C to +85°C.

Feature Summary

• Provides four independent differential drivers for RS-422 communication
• Features high electrostatic discharge protection rated at 15 kV
• Operates efficiently with low quiescent power consumption

Applications

• Industrial control systems requiring robust serial communication
• Power metering infrastructure equipment
• Security and access control networks

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing this variant. Confirm the manufacturer as Renesas Electronics Corporation or Intersil. Ensure the QFN-EP-24 package matches the design requirements. Validate RoHS compliance status through official documentation before integration.

Selection Notes

Select this component for designs requiring four differential outputs without integrated receivers. Verify that the 32 Mb/s speed meets system timing constraints. Ensure the PCB layout accommodates the thermal pad of the QFN-EP-24 package for adequate heat dissipation during operation.

Part Context

This device belongs to the ISL32179E series of interface integrated circuits. It serves as a specialized driver solution within Renesas's portfolio of industrial communication components. The part is designed to replace legacy discrete driver solutions in compact form factors.

Replacement Considerations

Check for direct pin-compatible alternatives within the same RS-422 driver family. Verify if updated revisions offer improved thermal performance or different packaging options while maintaining electrical specifications.
