ICL3222ECV-T

Overview

The ICL3222ECV-T is a low-power RS-232 transceiver manufactured by Renesas Electronics Corporation, designed for operation with single-supply voltages ranging from 3 V to 5.5 V. It integrates two receivers and one driver within a TSSOP-20 surface-mount package. The device supports data rates up to 500 kb/s and features an active current consumption of approximately 1 mA. It includes a shutdown mode to minimize power usage when the system is idle. The component provides ESD protection rated at 15 kV and operates reliably across a commercial temperature range of 0°C to +70°C.

Feature Summary

• Integrates dual receivers and a single driver for bidirectional serial communication
• Supports 3 V and 5 V logic levels with integrated charge pump circuitry
• Includes a dedicated shutdown pin to reduce quiescent current significantly

Applications

• Portable battery-powered equipment requiring low standby power
• Industrial control systems utilizing RS-232 communication protocols
• Embedded devices needing robust ESD protection on serial interfaces

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging rather than tube packaging when sourcing components. Confirm that the manufacturer designation aligns with Renesas Electronics Corporation following corporate acquisitions. Ensure compliance with RoHS directives and moisture sensitivity level requirements during storage and handling procedures.

Selection Notes

Select this component when a single driver and dual receiver configuration is required for RS-232 links. Consider the 500 kb/s data rate limit for high-speed applications. Evaluate the TSSOP-20 footprint against available PCB space constraints. Verify that the 3 V to 5.5 V supply range matches the target system voltage architecture.

Part Context

This part belongs to the ICL3222 series of RS-232 interface ICs. It shares functional similarities with other members of the family but differs in package type and reel configuration. The 'ECV' designation typically denotes the specific thermal and electrical characteristics associated with the TSSOP-20 variant within the product line.

Replacement Considerations
