ICL3310EIB

Overview

The ICL3310EIB is a dual RS-232 transceiver manufactured by Intersil, operating within a supply voltage range of 3.0V to 5.5V. It features an integrated charge pump that generates compliant ±5V output levels from a single low-voltage supply. The device supports data rates up to 125kbps and includes enhanced automatic powerdown functionality to minimize current consumption during idle periods. Packaged in a 16-pin SOIC format, it provides one driver and two receivers with ESD protection on bus pins.

Feature Summary

• Integrated charge pump eliminates the need for external bipolar supplies
• Enhanced automatic powerdown reduces quiescent current significantly
• Bus pins feature high electrostatic discharge protection ratings

Applications

• Portable battery-powered equipment requiring low power consumption
• Industrial control systems utilizing RS-232 communication
• Modems and portable instruments with serial interfaces

Procurement Notes

Verify the specific suffix 'IIB' against official Renesas or Intersil documentation to confirm package type and temperature grade. Confirm end-of-life status as this series may be discontinued. Ensure compliance with export restrictions if applicable to the region. Validate RoHS compliance through the manufacturer's latest certification documents before procurement.

Selection Notes

Select this component when designing systems requiring dual RS-232 channels from a single 3V or 5V supply. The low standby current makes it suitable for battery-operated devices. Verify that the required data rate does not exceed 125kbps. Ensure the application environment falls within the specified industrial temperature range for the 'I' suffix variant.

Part Context

This part belongs to the ICL32XXE family of RS-232 transceivers known for low power operation. These devices are designed to replace traditional multi-supply solutions. The 'E' suffix typically denotes enhanced features such as improved ESD protection and lower power modes compared to earlier generations.

Replacement Considerations

Direct replacements include other members of the ICL32XXE family such as the ICL3220E or ICL3230E, provided pin compatibility and functional requirements match. Verify that substitute parts maintain the same 16-pin SOIC footprint and support the necessary data rates.
