ICL3223ECAZ-T

Overview

The ICL3223ECAZ-T is a dual driver, dual receiver RS-232 transceiver manufactured by Renesas Electronics. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 250 kb/s. The device features full-duplex communication with single-ended receiver signal types. It includes automatic power-down functionality and provides 15 kV ESD protection on all pins. The component is housed in an SSOP-20 package and is designed for surface mount installation. Operating temperatures range from 0°C to +70°C, with a typical operating supply current of 1 mA.

Feature Summary

• Automatic power-down function reduces standby current when the cable is removed or peripheral is off
• Integrated charge pumps enable operation with small external capacitors
• Provides 15 kV electrostatic discharge protection on all RS-232 lines

Applications

• Portable computers and notebook systems requiring low power consumption
• Personal digital assistants (PDAs) with serial communication interfaces
• Battery-powered devices utilizing 3.3 V or 5 V logic levels

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging versus tube variants. Confirm RoHS compliance status through official documentation as availability may vary. Check for moisture sensitivity level requirements during storage and handling. Ensure the SSOP-20 footprint matches the target PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component for applications requiring dual drivers and receivers with automatic power management. Compare against ICL3221 for single channel needs or ICL3243 for triple driver configurations. Verify compatibility with 3.3 V and 5.0 V mixed voltage systems. Consider the 250 kbps speed limit when designing high-speed serial links.

Part Context

This part belongs to the ICL32xx family of one microamp supply current RS-232 transmitters and receivers. The family includes variants like ICL3221, ICL3222, ICL3232, and ICL3241. These devices are engineered for low-power portable electronics where standby current conservation is critical. The ICL3223 specifically offers a balanced two-driver, two-receiver configuration.

Replacement Considerations

Public confirmed substitutes include ICL3223ECAZ for tube packaging. Cross-reference with ISL3223ECAZ for identical functional specifications. Verify pinout compatibility with legacy Intersil designs before substitution.
