ICL3226CA-T

Overview

The ICL3226CA-T is a single-driver, single-receiver RS-232 transceiver from the ICL32xxE series by Renesas Electronics. It operates on a single power supply ranging from 3V to 5.5V and supports data rates up to 500 kb/s. The device features an enhanced automatic powerdown mode that reduces supply current to 1 mA during idle periods. It utilizes internal charge pumps requiring only four external 0.1μF capacitors for voltage generation. The component is housed in a 16-pin SSOP package and is designed for surface-mount installation.

Feature Summary

• Enhanced automatic powerdown functionality significantly reduces power consumption when no signal activity is detected
• Integrated charge pump circuitry minimizes external component count by requiring only four small capacitors
• Receiver input hysteresis provides improved immunity against noise interference on communication lines

Applications

• Battery-powered portable equipment and handheld devices
• Laptop computers and notebook systems
• Modems and peripheral interfaces

Procurement Notes

Verify the specific suffix 'CA' against official Renesas documentation to confirm temperature range and packaging details. Confirm availability status as some variants may be discontinued or have limited stock. Ensure the tape-and-reel format matches automated assembly requirements. Check for moisture sensitivity level compliance before storage.

Selection Notes

Select this component for applications requiring low-power RS-232 connectivity with minimal external parts. Compare against MAX3224 or MAX3226 equivalents if drop-in replacement is needed. Verify that the 500 kb/s data rate meets system timing requirements. Ensure the 3V to 5.5V supply range aligns with the target board's power architecture.

Part Context

This part belongs to the ICL32xxE family of CMOS RS-232 transceivers known for low power consumption. The 'T' suffix typically indicates tape-and-reel packaging suitable for high-volume surface-mount production. The CA variant specifies commercial temperature performance within the broader product line.

Replacement Considerations

MAX3224 and MAX3226 are documented as pin-compatible drop-in replacements. Verify electrical parameters such as slew rate and output voltage levels match application needs before substitution.
