ICL3223CP

Overview

The ICL3223CP is a dual transmitter and receiver RS-232 transceiver manufactured by Renesas Electronics Corporation. It operates from a single 3V to 5.5V power supply and meets EIA/TIA-232 and V.28/V.24 standards. The device features two drivers and two receivers, providing full-duplex communication capabilities. It is housed in a 20-pin DIP package and is designed for surface mount or through-hole installation. The component supports data rates up to 120 kb/s and includes 15 kV ESD protection on all pins.

Feature Summary

• Dual driver and receiver configuration for full-duplex RS-232 communication
• Single 3.0V to 5.5V power supply operation
• Compliance with EIA/TIA-232 and V.28/V.24 interface standards
• Integrated 15 kV electrostatic discharge (ESD) protection

Applications

• Industrial equipment serial communication interfaces
• Modem and portable instrument connections
• Point-of-sale (POS) terminal data transmission
• Computer peripheral connectivity

Procurement Notes

Verify the specific suffix 'CP' indicates the 20-pin DIP package variant. Confirm the manufacturer as Renesas Electronics America Inc. Check for obsolete status notifications, as this part may be discontinued. Ensure compatibility with existing 3V to 5.5V system voltages. Validate pinout alignment for direct replacement scenarios.

Selection Notes

Select this component when dual-channel RS-232 communication is required within a single IC footprint. It is suitable for designs needing robust ESD protection without external components. Consider the 20-pin DIP package for through-hole manufacturing processes. Evaluate the 120 kb/s data rate against application speed requirements. Ensure the 3V to 5.5V supply range matches the target system voltage.

Part Context

The ICL3223 belongs to the ICL32xx series of RS-232 transceivers from Renesas. This family provides reliable serial communication solutions for industrial and commercial applications. The CP suffix typically denotes the plastic dual in-line package format. Similar variants include the ICL3222E and ICL3224E, which offer different channel configurations.

Replacement Considerations

Public confirmed substitute part numbers include ICL3222CP and ICL3224CP from Renesas. Cross-reference pinouts before substitution. Verify that alternative devices meet the same EIA/TIA-232 standards. Check operating temperature ranges for environmental compatibility.
