ISL32272EFVZ

Overview

The ISL32272EFVZ is a quad RS-422 driver manufactured by Renesas Electronics Corporation, housed in a 16-lead TSSOP package. It supports data rates up to 10 Mb/s with a supply voltage range of 3 V to 5.5 V and operates within an extended temperature range of -40°C to +125°C. The device features low quiescent current of 800 µA and includes ±15 kV ESD protection on all pins. It is designed for high-speed differential bus communication applications requiring robust noise immunity.

Feature Summary

• Provides four independent differential drivers for RS-422 compliant communication
• Features integrated electrostatic discharge protection rated at ±15 kV
• Supports operation across industrial temperature ranges up to +125°C

Applications

• Industrial control systems requiring reliable serial communication
• Building automation networks utilizing RS-422 protocols
• Data acquisition modules in harsh electromagnetic environments

Procurement Notes

Verify the specific suffix 'FVZ' corresponds to the TSSOP-16 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure supply chain partners provide valid traceability records for components intended for critical infrastructure deployments.

Selection Notes

Select this component when a quad-driver configuration is required without integrated receivers. Compare against the ISL32273 series if bidirectional transceiver functionality is needed instead of unidirectional driving. Evaluate power consumption requirements against the specified 800 µA quiescent current limit for battery-operated designs.

Part Context

This part belongs to the ISL3227xE family of interface ICs from Renesas. It shares architectural similarities with other members like the ISL32272EFBZ but differs in package type. The series is characterized by high-speed performance and enhanced ESD resilience suitable for demanding industrial interfaces.

Replacement Considerations

The ISL32272EFVZ-T serves as the tape-and-reel equivalent for automated assembly processes. Verify pinout compatibility before substituting with generic RS-422 drivers, as ESD ratings and slew rates may vary significantly between manufacturers.
