ISL32272EIVZ-T

Overview

The ISL32272EIVZ-T is a quad RS-422 driver manufactured by Renesas Electronics Corporation, belonging to the ISL32272E series. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 10 Mb/s. The device features four drivers with no integrated receivers, drawing an operating supply current of 800 uA. It provides ±15 kV ESD protection on all pins and functions reliably across an extended temperature range from -40 °C to +125 °C. The component is housed in a 16-lead TSSOP package and is supplied in tape and reel format.

Feature Summary

• Provides high-speed differential signaling for RS-422 communication networks
• Features robust electrostatic discharge protection rated at ±15 kV on all pins
• Operates efficiently with low quiescent current consumption
• Supports wide industrial temperature ranges for harsh environments

Applications

• Industrial automation control systems
• Factory floor networking equipment
• Process control instrumentation
• Data acquisition modules

Procurement Notes

Verify the specific suffix IVZ to confirm the TSSOP-16 package type, as other suffixes may indicate different packaging or lead-free status. Confirm RoHS compliance details directly with the manufacturer documentation. Check for End-of-Life notices or production discontinuation announcements, as availability may be limited for older Intersil-derived part numbers. Ensure moisture sensitivity level handling procedures are followed during storage and assembly.

Selection Notes

Select this component when a quad RS-422 driver is required without integrated receivers. Compare against the ISL32272EFBZ variant if an SOIC-Narrow-16 package is preferred instead of TSSOP. Verify that the 10 Mb/s data rate meets system requirements, as higher-speed alternatives like the ISL32172 exist. Ensure the 3 V to 5.5 V supply range aligns with the target board power rails.

Part Context

This part belongs to the ISL32272E family of RS-422 interface ICs originally developed by Intersil and now managed by Renesas Electronics. The series focuses on providing reliable differential transmission for industrial applications. The 'E' designation typically indicates enhanced ESD protection capabilities compared to standard variants. The product line supports various package options including SOIC and TSSOP to accommodate different PCB layout constraints.
