ICL3310CB

Overview

The Intersil ICL3310CB is a triple line transceiver designed for RS-232 communication, conforming to EIA/TIA-232-F and V.28/V.24 standards. It operates from a single +5V supply with an internal charge pump that generates the required positive and negative voltages for full RS-232 compliance. The device features three drivers and five receivers, offering high output drive capability of ±7V and low input thresholds of ±0.2V for noise immunity. It includes thermal shutdown protection and is housed in a 28-pin SSOP package.

Feature Summary

• Integrated charge pump eliminates external capacitors for voltage generation
• High noise immunity with low receiver input thresholds
• Thermal shutdown protection prevents damage during overload conditions

Applications

• Industrial control systems requiring serial communication
• Modem interfaces and data transmission equipment
• Point-of-sale terminals and barcode scanners

Procurement Notes

Verify the specific suffix 'CB' against the manufacturer's current datasheet to confirm the package type and temperature range. Ensure compatibility with system voltage levels and signal integrity requirements before procurement. Cross-reference the RoHS status and lead-free designation with the latest component certification documents.

Selection Notes

Select this component when a triple driver and five receiver configuration is required for RS-232 applications. Consider the internal charge pump for simplified board space compared to external capacitor solutions. Evaluate the operating temperature range and package constraints against the target environment specifications.

Part Context

The ICL3310 belongs to the Intersil family of RS-232 transceivers, which are widely used in legacy and industrial serial communication interfaces. This series provides reliable data transmission over standard DB9 connectors. The CB suffix typically denotes a specific plastic surface-mount package variant within the product line.

Replacement Considerations

Direct replacements include the MAX3232 or SP3232E for similar functionality. Verify pin-to-pin compatibility and electrical characteristics such as drive strength and quiescent current. Ensure the substitute supports the same voltage range and interface standards.
