ICL3223IAZ-T

Overview

The ICL3223IAZ-T is a single-driver, dual-receiver 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 500 kb/s. The device features an automatic power-down mode that reduces the operating supply current to approximately 1 mA. It is housed in a 20-lead SSOP package and is rated for industrial temperatures between -40°C and +85°C. The component includes ESD protection and complies with EIA/TIA-232 and V.28/V.24 specifications.

Feature Summary

• Integrates one driver and two receivers for bidirectional serial communication
• Includes automatic power-down functionality to minimize active current consumption
• Provides electrostatic discharge protection on input and output lines

Applications

• Industrial equipment requiring RS-232 connectivity
• Portable battery-powered instruments
• Modems and communication terminals

Procurement Notes

Verify the specific suffix 'T' indicates reel packaging when sourcing. Confirm the 'IAZ' designation corresponds to the industrial temperature grade and lead-free compliance requirements. Ensure the supplier provides valid RoHS documentation matching the manufacturer's current standards before finalizing orders.

Selection Notes

Select this component when a single driver and dual receivers are required for RS-232 links. It is suitable for designs needing low standby current through automatic power-down. Verify that the 500 kb/s data rate meets system timing requirements and that the SSOP-20 footprint fits the PCB layout constraints.

Part Context

This part belongs to the ICL3223 series of RS-232 transceivers from Renesas. It shares core architecture with other members like the ICL3223E but differs in package type and temperature rating. The series is designed for applications requiring reliable serial communication with reduced power consumption.

Replacement Considerations

Check for direct equivalents such as the ICL3223EIV or ICL3223CAZ if pin compatibility is critical. Verify that any substitute maintains the same driver/receiver count and voltage range.
