ICL3223IVZ

Overview

The ICL3223IVZ 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 with single-ended receiver signal types. Key electrical specifications include a maximum operating current of 1 mA and ESD protection rated at 15 kV. It functions reliably across an industrial temperature range from -40 °C to +85 °C. The component is housed in a TSSOP-20 surface-mount package.

Feature Summary

• Integrated automatic power-down mode that reduces standby current when the RS-232 cable is disconnected or peripheral devices are powered off.
• Built-in charge pump circuitry enabling operation from a single 3 V to 5.5 V power supply without external components.
• Robust electrostatic discharge protection on both transmitter outputs and receiver inputs to safeguard against high-voltage events.

Applications

• Portable computing devices such as laptops and notebooks requiring low-power serial connectivity.
• Personal digital assistants (PDAs) and handheld computers where space and power efficiency are critical.
• Industrial control systems operating in harsh environments with potential ESD exposure.

Procurement Notes

Verify the specific suffix 'IVZ' to confirm the industrial temperature grade (-40°C to +85°C) and tube packaging format. Ensure compatibility with the target PCB footprint for the TSSOP-20 package. Confirm moisture sensitivity level requirements during storage and handling procedures before assembly.

Selection Notes

Select this component for applications requiring dual-channel RS-232 communication with minimal quiescent current. It is suitable for systems needing automatic shutdown capabilities to extend battery life in portable electronics. Consider the TSSOP-20 package size constraints and verify that the 250 kb/s data rate meets the system's throughput requirements.

Part Context

This part belongs to the ICL3223E series of RS-232 transceivers designed for low-voltage operation. The series is characterized by its ability to maintain compliance with EIA/TIA-232 standards even at lower supply voltages. It represents a transition toward energy-efficient interface solutions for mobile and embedded applications.

Replacement Considerations

Check for ICL3223EIVZ-T if reel or cut-tape packaging is required instead of tubes. Verify pinout compatibility with other dual-driver RS-232 transceivers in the same package family before substitution.
