ISL32272EFVZ-T

Drivers, Receivers, Transceivers Overview

The ISL32272EFVZ-T is a quad RS-422 driver integrated circuit manufactured by Renesas Electronics. 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 an operating supply current of 800 uA. It provides ±15 kV electrostatic discharge (ESD) protection on all pins. The component is rated for extended industrial temperatures, functioning from -40 °C to +125 °C. It is housed in a 16-lead Thin Shrink Small Outline Package (TSSOP) and is supplied in reel packaging.

Drivers, Receivers, Transceivers Feature Summary

• Quad differential driver architecture designed for RS-422 communication standards
• Robust ±15 kV ESD protection across all signal pins
• Extended temperature rating suitable for harsh industrial environments

Drivers, Receivers, Transceivers Applications

• Industrial automation control systems
• Factory floor sensor networks
• Building automation and HVAC controllers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status through official datasheets or manufacturer declarations. Check for moisture sensitivity level requirements during storage and handling. Ensure the TSSOP-16 footprint matches the target PCB design constraints. Validate that the 10 Mb/s speed meets system timing requirements.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad driver topology is required for RS-422 applications. Consider the 800 uA quiescent current for power-sensitive designs. Verify compatibility with 3.3 V and 5 V logic levels. Ensure the 125 °C maximum junction temperature aligns with thermal management strategies. Compare against single or dual driver alternatives if fewer channels are sufficient.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL32272E series of RS-422 interface ICs. It serves as the transmitter counterpart to receiver-only devices like the ISL32273E. The series emphasizes high reliability and noise immunity for serial communication buses. It complements other interface solutions in the Renesas portfolio for robust data transmission.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible substitutes may include other quad RS-422 drivers from the same family, such as the ISL32272EFBZ-T in SOIC package. Cross-reference electrical specifications including voltage ranges and ESD ratings before substitution.
