ISL3232EIRZ-T

Drivers, Receivers, Transceivers Overview

The ISL3232EIRZ-T is a full-duplex RS-232 transceiver manufactured by Renesas Electronics Corporation. It integrates two drivers and two receivers in a single package, supporting data rates up to 250 kbps. The device operates on a single power supply ranging from 2.7 V to 5.5 V. It features 15 kV ESD protection on all pins and includes a shutdown mode for low power consumption. The component is housed in a 16-lead QFN (5x5 mm) surface-mount package and is rated for an operating temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrates dual drivers and dual receivers for full-duplex communication
• Provides robust 15 kV electrostatic discharge protection on all signal pins
• Supports low-power operation through an integrated shutdown mode

Drivers, Receivers, Transceivers Applications

• Portable equipment requiring RS-232 connectivity
• Modems and fax machines
• Industrial control systems with serial interfaces
• Handheld terminals and barcode scanners

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix T indicates tape-and-reel packaging when ordering. Confirm the QFN-16 footprint matches the design layout. Check RoHS compliance status as per current manufacturer declarations. Ensure voltage levels align with system requirements within the 2.7 V to 5.5 V range.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs needing compact size due to the small QFN package. Consider the 250 kbps speed limit for high-speed applications. Evaluate the 1 mA supply current against battery life constraints. Compare ESD ratings if harsh environmental conditions are expected.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL3232 family of RS-232 transceivers designed for low-voltage operation. It serves as a bridge between UART signals and RS-232 levels. The series emphasizes reliability and compactness for modern electronic devices.

Drivers, Receivers, Transceivers Replacement Considerations

ICL3232IVZ-T7A is a functional equivalent from Renesas but uses a 16-TSSOP package. Verify pin compatibility and thermal performance differences between QFN and TSSOP formats before substitution.
