ICL3222EIBZ

Overview

The ICL3222EIBZ is a CMOS RS-232 transceiver manufactured by Renesas Electronics, operating on a single 3V to 5.5V power supply. It integrates two drivers and two receivers for full-duplex communication with a data rate of 500 kb/s. The device features low quiescent current of 1 mA and includes a shutdown mode to minimize power consumption. It provides 15 kV ESD protection on all pins and operates within an industrial temperature range of -40°C to +85°C. The component is housed in a 16-pin SOIC-Wide package.

Feature Summary

• Integrated dual driver and dual receiver configuration for full-duplex RS-232 communication
• Low power operation with 1 mA typical quiescent current and dedicated shutdown control
• Robust electrostatic discharge protection rated at 15 kV across all signal pins

Applications

• Industrial equipment serial communication interfaces
• Portable battery-powered devices requiring low power consumption
• Embedded systems connecting to RS-232 peripherals

Procurement Notes

Verify the specific suffix 'BZ' against official Renesas documentation to confirm lead-free status and RoHS compliance details. Confirm package dimensions match the SOIC-Wide specification before integration. Check for obsolescence notices as this part may have limited availability or replacement recommendations from the manufacturer.

Selection Notes

Select this component when a 3V to 5.5V supply voltage is required for RS-232 interfacing. Ensure the application demands a 500 kb/s data rate and benefits from the integrated shutdown feature. Verify that the 16-pin SOIC-Wide footprint fits the PCB layout constraints compared to other package options like SSOP.

Part Context

The ICL3222 series belongs to Renesas's line of low-power RS-232 interface ICs derived from Intersil technology. This family focuses on reducing power consumption while maintaining compatibility with standard RS-232 protocols. The EIBZ variant specifically denotes the industrial temperature grade and wide SOIC packaging option within this product line.

Replacement Considerations

Consult Renesas datasheets for direct pin-compatible replacements such as the ISL3232E or similar members of the ICL3222 family. Verify electrical parameters and package dimensions before substitution.
