ICL232CPE

Overview

The Intersil ICL232CPE is a dual transmitter and receiver RS-232 line transceiver designed for low-power applications. It operates on a single 5V supply and supports data rates up to 120kbps. The device utilizes an internal charge pump requiring only four external capacitors, eliminating the need for dual voltage supplies. Housed in a 16-pin PDIP package with through-hole mounting, it meets EIA/TIA-232 specifications. The component features a minimum operating temperature of 0°C and a maximum of +70°C, ensuring reliable performance in standard commercial environments.

Feature Summary

• Integrated charge pumps generate required voltages using minimal external components
• Single 5V power supply operation simplifies system design
• Through-hole PDIP packaging facilitates prototyping and manual assembly

Applications

• RS-232 serial communication interfaces
• Modem connections
• Peripherals requiring standard serial ports

Procurement Notes

Verify the manufacturer origin as Intersil or its successor Renesas when sourcing. Confirm the specific suffix 'P' indicates the PDIP package variant. Ensure compliance with RoHS standards if required by the target application. Cross-reference datasheets to confirm pinout compatibility with existing designs before procurement.

Selection Notes

Select this component for systems requiring a drop-in replacement for legacy 5V RS-232 transceivers like the MAX232. It is suitable for applications where board space allows for through-hole mounting and power consumption is not the primary constraint compared to cost or availability. Verify that the 120kbps speed meets the baud rate requirements of the connected devices.

Part Context

This part belongs to the ICL232/ICL233 family of RS-232 transceivers. These devices are widely used as standard interface solutions for serial communications. The ICL232 variant specifically provides two drivers and two receivers, making it a common choice for basic serial port implementations in industrial and consumer electronics.

Replacement Considerations

• MAX232CPE
• SP232EEN

FAQ
