ICL3223ECV

Overview

The ICL3223ECV is a dual driver/receiver RS-232 transceiver manufactured by Intersil, now part of Renesas Electronics. It operates on a single 3.0V to 5.5V supply and complies with EIA/TIA-232 and V.28/V.24 standards. The device features enhanced automatic powerdown for low standby current. It provides 15kV electrostatic discharge (ESD) protection on all pins. The component is housed in a 20-pin SSOP package.

Feature Summary

• Enhanced automatic powerdown functionality reduces operating current during idle periods.
• Integrated charge pump eliminates the need for external capacitors for voltage generation.
• Robust 15kV ESD protection ensures reliability across all signal pins.

Applications

• Portable battery-powered equipment requiring low standby current
• Industrial control systems utilizing RS-232 communication
• Modems and data transmission devices

Procurement Notes

Verify the specific suffix 'ECV' against official Renesas/Intersil documentation to confirm package type and temperature range. Confirm availability status as this series may be discontinued or subject to last-time buy notices. Ensure compatibility with existing PCB footprints for the 20-pin SSOP configuration before ordering.

Selection Notes

Select this component when a dual-channel RS-232 interface is required with minimal quiescent current. It is suitable for designs needing 15kV ESD protection without external components. Compare against the ICL3223EIVZ if a TSSOP package is preferred instead of SSOP.

Part Context

This part belongs to the ICL3223E family of RS-232 transceivers designed for 3V to 5.5V operation. The family includes variants with different packages such as SSOP and TSSOP. These devices are widely used in legacy serial communication interfaces where low power consumption is critical.

Replacement Considerations

The ICL3223EIVZ serves as a direct functional alternative with an identical electrical specification but utilizes a TSSOP-20 package instead of SSOP-20. Verify pinout compatibility and thermal characteristics when substituting between these package types.
