ICL3223ECA-T

Overview

The ICL3223ECA-T is a dual transmitter and dual receiver RS-232 interface integrated circuit manufactured by Intersil. It operates within a supply voltage range of 3 V to 5.5 V, supporting standard 3.0 V and 5.0 V logic levels. The device provides two drivers and two receivers, facilitating full-duplex communication compliant with EIA/TIA-232 and V.28/V.24 specifications. It features enhanced automatic powerdown functionality to minimize current consumption during idle periods. The component is housed in a 20-lead SSOP package and is designed for commercial temperature operation.

Feature Summary

• Integrated dual driver and dual receiver architecture for full-duplex RS-232 communication
• Enhanced automatic powerdown mechanism reduces quiescent current consumption
• Operates across a wide single-supply voltage range from 3 V to 5.5 V
• Compliant with EIA/TIA-232 and V.28/V.24 interface standards

Applications

• Industrial control systems requiring reliable serial data transmission
• Portable battery-powered equipment utilizing low-power RS-232 interfaces
• Modems and communication terminals adhering to standard serial protocols
• Embedded systems interfacing with legacy RS-232 peripherals

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration distinct from bulk variants. Confirm RoHS compliance status through official manufacturer documentation as regulatory requirements evolve. Check for obsolescence notices or lifecycle changes directly from Renesas Electronics, as distribution availability may vary significantly across regions.

Selection Notes

Select this component when a dual-channel RS-232 transceiver with low-power standby modes is required. Ensure the application environment remains within the specified commercial temperature range. Verify that the system power supply aligns with the 3 V to 5.5 V operating window. Consider the SSOP-20 footprint constraints during PCB layout design to ensure adequate spacing for high-voltage RS-232 signals.

Part Context

This part belongs to the ICL3223 series of RS-232 transceivers, which are widely used in applications demanding robust serial communication over moderate distances. The series is characterized by its ability to operate efficiently on single supplies while generating the necessary higher voltages for RS-232 signaling internally. It serves as a bridge between microcontroller UARTs and standard serial ports.

Replacement Considerations

Direct replacements include the ICL3223ECA (non-tape variant) or equivalent RS-232 transceivers with identical pinouts and dual-driver/dual-receiver configurations. Verify functional compatibility regarding powerdown thresholds and output voltage levels before substitution.
