ICL3222EIAZ

Overview

The ICL3222EIAZ is a full-duplex RS-232 transceiver manufactured by Renesas Electronics Corporation. It integrates two drivers and two receivers within a single SSOP-20 package. The device operates on a single power supply ranging from 3 V to 5.5 V, supporting both 3.3 V and 5 V logic levels. It achieves data rates up to 500 kb/s with a typical operating supply current of 1 mA. The component provides 15 kV electrostatic discharge (ESD) protection on all RS-232 lines. It functions reliably across an extended industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates dual drivers and dual receivers for full-duplex communication in a compact surface-mount package.
• Provides robust 15 kV ESD protection on transmit and receive lines to safeguard connected equipment.
• Operates efficiently on a single low-voltage supply, reducing overall system power consumption.

Applications

• Industrial control systems requiring reliable serial communication interfaces.
• Portable battery-powered devices utilizing low-power RS-232 connectivity.
• Embedded systems interfacing microcontrollers with RS-232 peripherals.

Procurement Notes

Verify the specific suffix 'IAZ' confirms the SSOP-20 tube packaging and industrial temperature grade. Confirm RoHS compliance status through official Renesas documentation prior to integration. Ensure moisture sensitivity level handling procedures are followed during assembly to prevent package damage.

Selection Notes

Select this component when dual-channel RS-232 transmission is required with high ESD tolerance. Compare against similar models like ICL3225 if higher data rates or shutdown features are necessary. Verify that the 500 kb/s speed meets application requirements and that the SSOP-20 footprint fits the PCB layout constraints.

Part Context

This part belongs to the ICL3222 series of RS-232 interface ICs originally developed by Intersil and now produced by Renesas. The series is designed for low-power applications requiring reliable serial data transmission. It serves as a bridge between TTL/CMOS logic levels and RS-232 voltage standards.

Replacement Considerations

ICL3222EIAZ-T is available in tape-and-reel packaging for automated assembly. Other variants in the ICL322x family may offer different driver/receiver counts or additional features like shutdown modes.
