ICL3226CA

Overview

The ICL3226CA is a single-driver, single-receiver RS-232 transceiver manufactured by Intersil. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 500 kb/s. The device features enhanced automatic powerdown functionality, reducing operating current to 1 mA and standby current to 1 μA. It includes on-chip voltage converters requiring only four external 0.1 μF capacitors. The component provides ±15 kV ESD protection and meets EIA/TIA-232 specifications. It is housed in an SSOP-16 package with a commercial temperature range of 0°C to +70°C.

Feature Summary

• Enhanced automatic powerdown management for low-power operation
• Integrated charge pump requiring minimal external capacitance
• High electrostatic discharge tolerance for robust interface reliability

Applications

• Battery-powered portable equipment
• Laptop computers and notebooks
• Modems and peripheral devices

Procurement Notes

Verify the specific suffix 'CA' against official Renesas or Intersil documentation to confirm pinout compatibility and environmental compliance status. Confirm availability as this part may be discontinued or superseded by newer revisions. Ensure the source document explicitly lists the ICL3226CA variant rather than generic family members.

Selection Notes

Select this component for applications requiring a drop-in replacement for MAX3224 or MAX3226 devices. Verify that the system design accommodates the SSOP-16 package dimensions. Confirm that the required data rate does not exceed the specified 500 kb/s limit under the intended supply voltage conditions.

Part Context

This component belongs to the ICL3226 series of low-power RS-232 transceivers. It shares functional similarities with the ICL3224 and ICL3238 but differs in driver/receiver counts and pin configurations. The series is designed for battery-operated systems requiring efficient power management alongside standard serial communication capabilities.

Replacement Considerations

Publicly confirmed direct substitutes include MAX3224, MAX3226, and MAX3238. Verify pin-to-pin compatibility and electrical parameter alignment before implementation.
