ICL3223IA

Overview

The ICL3223IA is a dual driver, dual receiver RS-232 transceiver manufactured by Intersil. It operates on a single 3V to 5.5V supply and supports data rates up to 500 kb/s. The device features an industrial temperature range from -40°C to +85°C and includes automatic power-down functionality for low standby current. It utilizes small external capacitors and is housed in a 20-pin SSOP package.

Feature Summary

• Integrates two drivers and two receivers for full-duplex communication
• Supports high-speed data transmission up to 500 kb/s
• Includes automatic power-down mode to minimize power consumption
• Provides ESD protection for enhanced signal integrity

Applications

• Industrial control systems requiring reliable serial communication
• Portable battery-powered equipment utilizing low voltage supplies
• Modems and other RS-232 compliant interface devices

Procurement Notes

Verify the specific suffix against official Renesas or Intersil documentation to confirm exact pinout and electrical characteristics. Ensure the component meets RoHS compliance requirements for your region. Confirm moisture sensitivity levels and recommended reflow profiles before assembly.

Selection Notes

Select this component when a dual-channel RS-232 interface is required with low power consumption. It is suitable for designs needing operation across wide industrial temperature ranges. Compare against similar models like the ICL3223ECAZ if commercial temperature grades are sufficient.

Part Context

This part belongs to the ICL3223 series of line transceivers designed for RS-232 applications. It represents a transition from older CMOS technologies to more efficient solutions offering reduced capacitor sizes and lower operating currents while maintaining standard compatibility.

Replacement Considerations

The ICL3223ECAZ serves as a commercial grade alternative within the same family. Verify pin compatibility and temperature specifications before substitution.
