ICL232CBEZT

Overview

The ICL232CBEZT is a dual RS-232 transceiver manufactured by Renesas Electronics Corporation, designed for +5V powered applications. It integrates two drivers and two receivers within a single integrated circuit to facilitate full-duplex communication. The device supports data rates up to 120 kb/s and operates with a supply voltage range of 4.5 V to 5.5 V. It features an operating current of 10 mA and is housed in a 16-pin SOIC-Wide surface-mount package. The component is rated for operation between 0°C and +70°C and includes internal capacitors for charge pump functionality.

Feature Summary

• Integrates dual drivers and dual receivers for complete RS-232 signal conversion
• Supports full-duplex communication at data rates up to 120 kb/s
• Operates on a single +5V power supply with low standby current consumption
• Includes internal charge pump capacitors to generate required voltage levels

Applications

• Serial communication interfaces in industrial control systems
• Data transmission links in embedded computing devices
• Modem connections and peripheral interfacing in consumer electronics
• RS-232 port implementation in instrumentation equipment

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing from distributors. Confirm RoHS compliance status as some variants may differ. Check lead times due to potential end-of-life or obsolescence status associated with the ICL232 family. Ensure the supplier provides official datasheets matching the Renesas part number for accurate pinout and electrical parameter validation before integration.

Selection Notes

Select this component for designs requiring standard RS-232 signaling with minimal external passive components. The integrated charge pump simplifies board layout compared to discrete solutions. Consider the 16-SOIC package constraints for thermal management and PCB space. Verify that the 120 kb/s speed meets application requirements, as higher-speed alternatives exist within the broader interface IC portfolio if needed.

Part Context

This part belongs to the ICL232 series of dual transceivers originally developed by Intersil and now produced by Renesas Electronics. The series is widely recognized for its simplicity and reliability in legacy serial communication applications. The 'C' designation typically denotes commercial temperature range operation, while 'BEZ' specifies the wide-body SOIC package variant.

Replacement Considerations

The MAX232N from Texas Instruments is documented as a direct substitute. Both parts share similar functional characteristics and pinouts. Verify mechanical dimensions and electrical tolerances match the original design specifications before swapping components to ensure compatibility with existing PCB layouts and circuit performance.
