ICL3222EIVZ-T

Overview

The ICL3222EIVZ-T is a dual driver, dual receiver RS-232 transceiver manufactured by Renesas Electronics. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 250 kb/s. The device features full-duplex communication capability and includes an integrated shutdown mode that reduces operating power current to 1 mA. It provides ±15 kV electrostatic discharge (ESD) protection on both transmitter outputs and receiver inputs. The component is housed in a TSSOP-20 surface-mount package and is rated for an industrial operating temperature range from -40 °C to +85 °C.

Feature Summary

• Integrated shutdown functionality enables significant reduction in standby power consumption
• Robust ±15 kV ESD protection ensures signal line integrity against electrostatic events
• Single-ended receiver architecture simplifies interface design for standard RS-232 applications

Applications

• Portable computing devices requiring low-power serial communication
• Industrial control systems with mixed 3.3V and 5V logic levels
• Embedded systems utilizing RS-232 peripheral connections

Procurement Notes

Verify the specific suffix 'T' indicates reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure handling procedures account for moisture sensitivity classification during storage and assembly processes.

Selection Notes

Select this component for designs requiring dual-channel RS-232 connectivity with minimal quiescent current. The TSSOP-20 package suits space-constrained printed circuit board layouts. Verify that the 250 kb/s maximum data rate meets system timing requirements before finalizing the bill of materials.

Part Context

This part belongs to the ICL3222 series of RS-232 interface integrated circuits. The series is designed for compatibility with EIA/TIA-232 standards while supporting modern low-voltage logic families. The device serves as a bridge between microprocessor systems and legacy serial peripherals.

Replacement Considerations

Check datasheets for equivalent parts such as ADM232 or MAX232 variants. Ensure substitute components match the TSSOP-20 footprint and support the required 3V to 5.5V operating voltage range without altering pin configurations.
