ISL3232EIRZ-T7A

Overview

The ISL3232EIRZ-T7A is a full-duplex RS-232 transceiver manufactured by Renesas Electronics Corporation. It integrates two drivers and two receivers within a single QFN-16 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, with typical current consumption of 1 mA. It features ±15 kV ESD protection on all pins and meets RS-232 standards for signal levels. The component is rated for an operating temperature range of -40°C to +85°C and complies with RoHS directives.

Feature Summary

• Integrated dual driver and dual receiver architecture for full-duplex communication
• High electrostatic discharge (ESD) protection capability on all interfaces
• Single-supply operation compatible with standard voltage rails
• Compact surface-mount packaging suitable for space-constrained designs

Applications

• Industrial control systems requiring robust serial communication
• Portable instrumentation and medical devices
• Modem and communications equipment
• Point-of-sale terminals and barcode scanners

Procurement Notes

Verify the specific suffix 'T7A' indicates tape-and-reel packaging when ordering. Confirm the QFN-16 footprint matches the design layout. Check moisture sensitivity level handling requirements during assembly. Ensure the voltage range aligns with the target system's power supply specifications.

Selection Notes

Select this component for applications requiring full-duplex RS-232 connectivity in a small form factor. Compare against ICL3232 variants if TSSOP packaging is preferred over QFN. Consider the ISL3232EIBZ variant if SOIC-8 packaging is required instead. Verify ESD protection needs against specific environmental standards.

Part Context

This part belongs to the ISL3232E series of low-power RS-232 transceivers. It shares functional similarities with the ICL3232 but utilizes Intersil/Renesas branding and specific packaging options. The series is designed for battery-powered applications due to its low current consumption and wide supply voltage range.

Replacement Considerations

ICL3232IVZ-T7A offers identical electrical performance in a TSSOP-16 package. ISL3232EIBZ provides the same functionality in an SOIC-8 package. Verify pin compatibility and thermal characteristics when substituting between different package types.
