ICL3225ECAZ-T

Overview

The ICL3225ECAZ-T is a low-power RS-232 transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 1 Mbps. The device integrates two drivers and two receivers in a full-duplex configuration, housed in a 20-pin SSOP package. It features enhanced automatic powerdown functionality that reduces operating supply current to approximately 1 mA. The component provides ±15 kV electrostatic discharge (ESD) protection on all RS-232 lines and complies with EIA/TIA-232 standards.

Feature Summary

• Enhanced automatic powerdown circuitry significantly reduces power consumption during idle periods.
• Integrated charge pump generates required RS-232 voltage levels from a single low-voltage supply.
• Robust ±15 kV ESD protection ensures reliability across all signal interfaces.

Applications

• Portable battery-powered equipment requiring low standby current
• Industrial control systems utilizing RS-232 communication protocols
• Embedded systems interfacing with modems or serial peripherals

Procurement Notes

Verify the specific suffix 'ECAZ-T' against official Renesas documentation to confirm pinout compatibility and package dimensions. Ensure the procurement channel provides traceability for moisture sensitivity level handling. Confirm RoHS compliance status through the manufacturer's latest certification records before integration into regulated assemblies.

Selection Notes

Select this component when a dual-driver RS-232 interface is required with minimal quiescent current. Compare against the ICL3225EIAZ-T variant if extended industrial temperature ranges are necessary. Evaluate capacitor requirements based on the internal charge pump design to ensure stable operation at the target baud rate.

Part Context

This part belongs to the ICL3225E series of RS-232 transceivers designed for low-power applications. It succeeds earlier Intersil designs under the Renesas Electronics portfolio. The 'T' suffix indicates tape-and-reel packaging for automated assembly processes.

Replacement Considerations

The ICL3225EIAZ-T serves as a verified alternative offering extended temperature specifications. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
