ICL232IBEBI

Overview

The ICL232IBEBI is a dual driver and dual receiver RS-232 transceiver manufactured by Harris Corporation, now part of Renesas Electronics. It operates on a single +5V power supply and integrates charge pumps to generate the necessary positive and negative voltages for RS-232 communication without requiring external transformers. The device features low supply current consumption and is designed for applications requiring reliable serial data transmission over short distances. It supports data rates up to 120 kbps and includes protection against latch-up conditions exceeding ±15kV ESD according to ANSI/ESDA/JEDEC JS-001 standards.

Feature Summary

• Integrates dual drivers and dual receivers for bidirectional RS-232 communication
• Internal charge pump eliminates need for external inductors or transformers
• Operates from a single +5V power supply
• Provides high electrostatic discharge (ESD) protection

Applications

• Industrial control systems requiring serial communication
• Point-of-sale (POS) terminals
• Medical equipment with serial interfaces
• Computer peripherals and modems

Procurement Notes

Verify component authenticity due to discontinued status. Check for RoHS compliance as original Harris versions may not meet current environmental regulations. Confirm package integrity and pin alignment before soldering. Source only from authorized distributors or certified surplus suppliers to avoid counterfeit parts. Validate datasheet revisions match the specific batch production date.

Selection Notes

Select this component when a legacy RS-232 interface is required with minimal external passive components. Ensure the system design accommodates the +5V supply voltage constraint. Consider thermal dissipation if operating in enclosed environments. Verify that the 120 kbps data rate meets application timing requirements. Compare pin compatibility with modern replacements like the MAX232 series if redesign is an option.

Part Context

The ICL232 series was originally developed by Intersil and later acquired by Harris Corporation, which subsequently became part of Renesas Electronics. This component represents a standard solution for RS-232 level shifting in embedded systems during the late 20th century. It remains relevant in maintenance scenarios for older industrial and commercial equipment where backward compatibility is essential.

Replacement Considerations

Direct pin-compatible substitutes include the MAX232N from Texas Instruments. Other compatible alternatives may include the SP232E from Maxim Integrated. Verify electrical specifications and package dimensions before substitution.
