ICL3241EIA-T

Overview

The ICL3241EIA-T is a single-driver, five-receiver RS-232 transceiver from the ICL32xxE series by Renesas Electronics. It operates on a 3V to 5.5V supply and supports data rates up to 500 kb/s. The device features ±15kV ESD protection on all RS-232 pins, compliant with IEC61000-4-2 standards. It includes an internal charge pump requiring only 0.1µF capacitors. The part is housed in a 28-pin SSOP package and functions within a temperature range of -40°C to +85°C. Operating current is typically 1 mA.

Feature Summary

• Integrated charge pump enables operation with minimal external capacitance
• Provides robust electrostatic discharge protection on serial interface pins
• Supports low-power standby modes for battery-operated applications

Applications

• Personal Digital Assistants (PDAs)
• Laptop computers
• Portable computing devices

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets. Ensure the component matches the exact 28-SSOP footprint required for the design.

Selection Notes

Select this model for systems requiring one transmitter and multiple receivers. It is suitable for 3.3V and 5V mixed-voltage environments. Consider higher-speed variants if data rates exceed 500 kb/s. Verify thermal requirements against the specified operating temperature range.

Part Context

This component belongs to the ICL32xxE family of low-power RS-232 transceivers. It shares architectural similarities with parts like the ICL3241EIVZ but differs in package type and reel configuration. The series is designed for portable electronics where power efficiency and space savings are critical.

Replacement Considerations

ICL3241EIAZ is the tube-packaged equivalent. ICL3241EIVZ offers the same electrical specifications in a TSSOP-28 package.
