ICL3223EIVZ

Overview

The ICL3223EIVZ is a full-duplex RS-232 transceiver manufactured by Renesas Electronics Corporation, housed in a TSSOP-20 surface-mount package. 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 integrates two drivers and two receivers with an operating quiescent current of 1 µA. It features ±15 kV ESD protection on all RS-232 pins and includes automatic shutdown functionality to minimize power consumption. The component functions reliably across an industrial temperature range from -40 °C to +85 °C.

Feature Summary

• Automatic shutdown circuitry reduces standby power when the interface is inactive
• Integrated charge pump enables operation from a single low-voltage supply
• Robust electrostatic discharge protection ensures signal integrity in harsh environments

Applications

• Portable computing devices requiring low-power serial communication
• Industrial control systems utilizing RS-232 interfaces
• Embedded applications with strict power budget constraints

Procurement Notes

Verify the specific suffix 'IVZ' against official Renesas documentation to confirm the exact tape-and-reel or tube packaging configuration intended for your assembly process. Confirm that the moisture sensitivity level requirements align with your facility's floor life management protocols before procurement.

Selection Notes

Select this component when a dual-driver, dual-receiver RS-232 solution is required for space-constrained designs. Ensure the system voltage falls within the 3 V to 5.5 V range. Consider the automatic shutdown feature if battery life is critical, as it eliminates the need for manual control signals to enter low-power states.

Part Context

This part belongs to the ICL322xE series of low-power RS-232 transceivers. It shares architectural similarities with the ICL3221E and ICL3222E but differs in pinout and driver/receiver counts. The series is designed to replace legacy 5 V-only transceivers in modern 3.3 V and mixed-voltage systems.
