ISL32272EIVZ

Overview

The ISL32272EIVZ is an RS-422 interface integrated circuit manufactured by Renesas Electronics under the Intersil brand. It functions as a quad driver with zero receivers, supporting data rates up to 10 Mb/s. The device operates on a supply voltage range of 3 V to 5.5 V, drawing a typical operating current of 800 uA. It features robust ESD protection rated at 15 kV and is housed in a TSSOP-16 package. The component supports industrial temperature ranges from -40°C to +125°C and includes anneal processing for enhanced reliability.

Feature Summary

• Quad differential line drivers designed for RS-422 communication standards
• High electrostatic discharge protection capability for harsh environments
• Low power consumption suitable for battery-operated systems
• Extended temperature range operation for industrial applications

Applications

• Industrial automation control networks
• Multi-drop communication bus systems
• Factory floor sensor interfaces
• Data acquisition system transmitters

Procurement Notes

Verify the specific suffix 'IVZ' against the manufacturer's official datasheet to confirm the TSSOP-16 package variant and anneal specifications. Ensure compatibility with RoHS directives if required by the target assembly process. Confirm availability status directly with authorized distributors as production cycles may vary.

Selection Notes

Select this component when only transmission capability is required without onboard reception. Compare the 10 Mb/s speed limit against higher-speed alternatives like the ISL32172E series if faster data rates are needed. Verify that the TSSOP-16 footprint matches the PCB layout constraints and that the 3 V to 5.5 V supply range aligns with the system power architecture.

Part Context

This part belongs to the ISL32272E family of RS-422 drivers. It complements receiver-only variants such as the ISL32273EIVZ to form complete duplex communication links. The 'I' grade indicates extended industrial temperature performance, while the 'VZ' suffix denotes the specific tape-and-reel packaging format.

Replacement Considerations

The ISL32272EFVZ-T serves as a direct functional substitute within the same family, offering identical electrical characteristics but potentially differing in package style or manufacturing origin. Verify pinout compatibility before substitution.
