ICL3223ECV-T

Overview

The Intersil ICL3223ECV-T is a dual driver/receiver RS-232 transceiver designed for +3.0V to +5.5V power supplies. It features an integrated charge pump generating voltages of +/-6V to +/-12V from a single supply, eliminating the need for external components. The device supports data rates up to 250kbps and includes enhanced automatic powerdown circuitry that reduces operating current to approximately 1µA during idle periods. It provides 15kV ESD protection on all RS-232 lines and operates within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Integrated charge pump generates required RS-232 voltage levels without external inductors or transformers
• Enhanced automatic powerdown circuitry significantly reduces quiescent current during low-power states
• Provides robust 15kV electrostatic discharge protection on transmit and receive lines
• Maintains full RS-232 compliance across the specified wide supply voltage range

Applications

• Portable battery-powered equipment requiring low standby current
• Industrial control systems with exposed serial communication ports
• Embedded systems utilizing RS-232 interfaces for configuration or debugging
• Medical devices requiring high ESD immunity in compact form factors

Procurement Notes

Verify the suffix 'CV-T' corresponds to the TSSOP-20 package and tape-and-reel shipping format. Confirm RoHS compliance status through official Renesas documentation. Ensure the specific lot date code meets project requirements. Cross-reference the manufacturer part number with distributor listings to confirm availability and authenticity before finalizing procurement orders.

Selection Notes

Select this component when a dual-channel RS-232 interface is needed with minimal external bill of materials. It is suitable for designs prioritizing low power consumption via automatic shutdown features. Compare against higher-speed variants if data rates exceed 250kbps are required. Verify thermal performance within the 0°C to 70°C commercial range for the intended application environment.

Part Context

This part belongs to the ICL32XXE family of RS-232 transceivers known for enhanced power management. It shares functional similarities with other dual-driver models in the series but differs in package type and shipping configuration. The 'E' designation indicates enhanced features such as improved ESD protection and lower power consumption compared to legacy versions.

Replacement Considerations

Direct substitutes include other ICL3223 variants with different packages, such as ICL3223EIPZ (SOIC-20) or ICL3223EBNZ (SSOP-20). Verify pin compatibility and electrical specifications before substitution. Alternative manufacturers offer functionally equivalent parts, but ensure signal integrity and timing parameters match the original design requirements.
