ICL232CBEZ

Overview

The ICL232CBEZ is a dual driver and dual receiver RS-232 transceiver manufactured by Renesas Electronics. It operates within a supply voltage range of 4.5 V to 5.5 V, with a typical operating voltage of 5 V. The device supports full-duplex communication at data rates up to 120 kb/s. It is housed in a 16-pin SOIC-Wide package designed for surface mount installation. The component functions without integrated ESD protection and maintains an operating power current of 10 mA across an industrial temperature range from 0°C to +70°C.

Feature Summary

• Provides dual independent drivers and receivers for full-duplex RS-232 serial communication
• Integrates on-chip charge pumps requiring only external capacitors for voltage generation
• Designed for single 5V power supply operation compatible with standard logic levels

Applications

• RS-232 serial communication interfaces
• Modem connections
• Printer port interfacing

Procurement Notes

Verify the specific suffix 'CBEZ' against official Renesas documentation to confirm pinout and electrical characteristics match requirements. Note that this component is listed as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors or verify if replacement packages are offered under updated part numbers before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring dual-channel RS-232 transmission over short distances using a standard 5V logic supply. Ensure the application environment remains within the specified 0°C to +70°C operating temperature range. Verify that the lack of built-in ESD protection does not compromise system reliability in high-static environments.

Part Context

This device belongs to the ICL232 series of line transceivers produced by Renesas Electronics, formerly Intersil. It serves as a CMOS-compatible interface solution for connecting microprocessors or DSPs to RS-232 ports. The series is characterized by low power consumption and minimal external component requirements compared to older bipolar counterparts.

Replacement Considerations

Direct substitutes include the MAX232N from Texas Instruments. Other compatible alternatives may exist within the broader ICL232 family or equivalent RS-232 transceivers from different manufacturers, provided they share the same 16-pin SOIC package and electrical specifications.
