ICL3238EIVZ

Overview

The ICL3238EIVZ is a low-power RS-232 transceiver manufactured by Renesas Electronics Corporation, housed in a 28-pin TSSOP package. 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 integrates five drivers and three receivers, providing robust signal transmission for serial interfaces. It features ±15 kV electrostatic discharge (ESD) protection on all RS-232 pins, ensuring reliability in portable applications. The component functions across an industrial temperature range from -40 °C to +85 °C with a typical operating supply current of 1 mA.

Feature Summary

• Integrated ESD protection rated at ±15 kV on driver outputs and receiver inputs.
• Supports operation with single 3-V or 5-V power supplies using efficient charge pumps.
• Includes manual shutdown mode to minimize standby power consumption.

Applications

• Portable computers and notebook systems requiring low-power serial connectivity.
• Personal digital assistants (PDAs) and handheld devices.
• Industrial control systems operating in harsh environments.

Procurement Notes

Verify the specific suffix 'IVZ' against the manufacturer's official datasheet to confirm the exact package type and temperature grade. Confirm end-of-life status as distribution channels may vary. Ensure compliance with RoHS directives if required for the target assembly process. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when designing systems requiring five transmit channels and three receive channels for RS-232 communication. It is suitable for applications needing high ESD immunity without external protection circuits. Consider the 28-TSSOP footprint for space-constrained printed circuit board layouts. Verify that the 250 kb/s data rate meets the system's baud rate requirements.

Part Context

This device belongs to the Intersil ICL32xxE series of RS-232 transceivers, which are designed for low-voltage operation. The series is characterized by its ability to maintain EIA/TIA-232 compliance even at 3.0 V supply voltages. The ICL3238 variant specifically provides a 5-driver and 3-receiver configuration, distinguishing it from other members of the family that may offer different channel counts.

Replacement Considerations

The MAX3238EIPWR from Texas Instruments offers equivalent electrical specifications and pinout compatibility. Both devices provide five drivers and three receivers with similar ESD protection levels. Verify package dimensions and thermal characteristics before substituting to ensure mechanical fit.
