ICL3223ECVZ-T

Overview

The ICL3223ECVZ-T is a dual-driver, dual-receiver RS-232 transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3 V to 5.5 V and supports full-duplex communication at data rates up to 250 kb/s. The device features an operating supply current of 1 mA and includes automatic power-down functionality to minimize energy consumption during idle periods. It provides enhanced electrostatic discharge protection rated at 15 kV on both transmitter outputs and receiver inputs. The component is housed in a TSSOP-20 surface-mount package and is designed for operation across a temperature range from -40 °C to +85 °C.

Feature Summary

• Integrated automatic shutdown mechanism reduces power consumption when the interface is inactive
• Robust ±15 kV electrostatic discharge protection on all signal pins ensures reliability in high-interference environments
• Single-ended output configuration compatible with standard RS-232 signaling requirements

Applications

• Portable battery-powered equipment requiring low standby current
• Industrial control systems utilizing RS-232 serial communication
• Embedded devices interfacing with modems or peripheral instruments

Procurement Notes

Verify the specific suffix 'CVZ-T' against official Renesas documentation to confirm the reel packaging format and tape specifications. Ensure the procurement channel sources components directly from authorized distributors to guarantee authenticity and traceability. Cross-reference the manufacturer part number with the Mouser designation 968-ICL3223EIVZ-T if sourcing through third-party platforms. Confirm RoHS compliance status via the latest datasheet revision before finalizing orders.

Selection Notes

Select this component when a dual-channel RS-232 solution is required for space-constrained designs using TSSOP-20 packages. It is suitable for applications needing 250 kb/s throughput with minimal quiescent current draw. Compare against single-driver variants like the ICL3221 if only one transmit/receive pair is necessary. Consider the ICL3225ECPZ if through-hole mounting or higher data rates are preferred over the surface-mount form factor.

Part Context

This part belongs to the ICL32XXE series of low-power RS-232 transceivers originally developed by Intersil and now managed by Renesas Electronics. The series is characterized by its ability to operate efficiently on single supplies while maintaining compatibility with legacy EIA/TIA-232 standards. The 'E' designation typically indicates enhanced ESD protection capabilities compared to earlier generations.

Replacement Considerations

The Maxim Integrated MAX3223EUP-TG1Z serves as a functional equivalent offering similar electrical characteristics and auto-shutdown features. The Texas Instruments TRS3223CPWR provides comparable dual-driver performance but may differ in thermal limits and package dimensions.
