ICL3221EIAZ

Overview

The ICL3221EIAZ is a single driver and receiver RS-232 transceiver manufactured by Renesas Electronics. It operates within a supply voltage range of 3V to 5.5V, supporting both 3.3V and 5V logic systems. The device provides full-duplex communication with a data rate of 500 kb/s and features an automatic powerdown function that reduces standby current to 1 µA. It includes ±15 kV ESD protection on RS-232 pins and meets EIA/TIA-232 and V.28/V.24 specifications. Packaged in a 16-pin SSOP, it operates from -40°C to +85°C.

Feature Summary

Automatic powerdown circuitry for low standby current consumption
Integrated charge pumps requiring only small external capacitors
Robust ±15 kV ESD protection on all RS-232 I/O pins
Compliance with EIA/TIA-232 and V.28/V.24 standards at 3V operation

Applications

Portable computers and notebook peripherals
Personal Digital Assistants (PDAs) and Palmtops
ISDN Terminal Adaptors
Battery-powered industrial control systems

Procurement Notes

Verify the specific suffix 'IAZ' confirms the industrial temperature range (-40°C to +85°C) and tube packaging. Confirm RoHS compliance status through official manufacturer documentation or certified distributor declarations. Ensure the ordering part number matches the required package type and thermal grade before finalizing procurement contracts.

Selection Notes

Select this component when a single-channel RS-232 interface is required for 3V or 5V systems. It is suitable for applications prioritizing low power consumption due to its automatic shutdown feature. Compare against the ICL3221EIAZ-T variant if reel packaging is preferred over tubes for surface mount assembly processes.

Part Context

This device belongs to the ICL32xxE series of low-power RS-232 transceivers. It serves as a direct replacement for legacy 5V devices like the MAX207E while enabling operation at lower voltages. The ICL3221EIAZ specifically offers one driver and one receiver configuration within the broader family of multi-driver options.
