ICL3222EIVZ

Overview

The ICL3222EIVZ is a full-duplex RS-232 transceiver manufactured by Renesas Electronics. It operates within a supply voltage range of 3 V to 5.5 V, supporting both 3.3 V and 5 V logic systems. The device integrates two drivers and two receivers with a data rate capability of 250 kb/s. It features low power consumption with an operating supply current of 1 mA and includes a shutdown mode for extended battery life. The component provides 15 kV electrostatic discharge (ESD) protection on all pins. It is housed in a TSSOP-20 surface-mount package and functions reliably across an industrial temperature range from -40 °C to +85 °C.

Feature Summary

• Integrated dual driver and dual receiver configuration for full-duplex communication
• High ESD protection rating of 15 kV on all signal pins
• Low power operation with dedicated shutdown mode functionality
• Single-ended receiver input compatibility

Applications

• Industrial serial communication interfaces
• Portable equipment requiring low power RS-232 connectivity
• Data acquisition systems
• Modem interface circuits

Procurement Notes

Verify the specific suffix 'EIVZ' against official Renesas documentation to confirm the TSSOP-20 package and industrial temperature grade. Ensure that procurement channels provide genuine components with traceable origin. Check for moisture sensitivity labeling as indicated in distributor specifications. Confirm RoHS compliance status through the manufacturer's latest product change notices or datasheet declarations before finalizing orders.

Selection Notes

Select this component when designing systems requiring a 3 V to 5.5 V powered RS-232 interface with moderate data rates up to 250 kb/s. It is suitable for applications needing robust ESD protection and low standby current due to its shutdown feature. Consider the TSSOP-20 footprint constraints during PCB layout. Compare against other members of the ICL3222 family if different packaging options like SSOP-20 or varying driver counts are required for the specific design.

Part Context

The ICL3222EIVZ belongs to the broader ICL3222 series of RS-232 transceivers produced by Renesas Electronics, formerly Intersil. This series offers various configurations including single and dual driver/receiver setups. The EIVZ designation specifically identifies the version with the TSSOP-20 package and industrial temperature rating. Other variants in the series may offer different data rates or packaging styles such as SSOP-20 or tube packaging instead of reels.

Replacement Considerations

Direct substitutes within the same series include ICL3222EIAZ, which shares identical electrical characteristics but utilizes an SSOP-20 package. Designers must verify pinout compatibility and physical dimensions when swapping between TSSOP-20 and SSOP-20 packages. Other ICL3222 variants with different driver counts or temperature ranges require schematic and layout review.
