ICL3232ECBN-T

Overview

The ICL3232ECBN-T is a dual RS-232 transceiver manufactured by Renesas Electronics. It operates on a single power supply ranging from +3V to +5.5V and meets EIA/TIA-232 and V.28/V.24 specifications. The device features ±15kV ESD protection, a maximum data rate of 250kbps, and a low standby current of 1µA. Packaged in a 16-pin SOIC format, it integrates an efficient charge pump requiring only four external 0.1µF capacitors.

Feature Summary

• Integrated high-voltage ESD protection for robust signal integrity
• Automatic power-down mode reduces current consumption during idle states
• Single-supply operation compatible with 3.3V and 5.0V systems

Applications

• Portable computing devices such as PDAs and laptops
• Battery-powered handheld equipment
• Modems and peripheral interfaces

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm package type and temperature range. Ensure the component matches the required RoHS compliance standards for your manufacturing process. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring RS-232 connectivity with strict power constraints. It serves as a direct upgrade or pin-compatible replacement for legacy Intersil devices. Verify that the application environment supports the specified operating temperature range and voltage levels to ensure reliable communication performance.

Part Context

This part belongs to the ICL3232 series of RS-232 transmitters and receivers. The series includes variants like ICL3232EIV and ICL3232ECAZ, sharing core electrical characteristics but differing in packaging and thermal ratings. The 'EC' designation typically indicates commercial grade performance within the broader product family.

Replacement Considerations

The ICL3232CBNZ is a documented functional substitute within the same series. Both parts share identical electrical specifications and pinouts. Verify that the alternative package variant meets the physical footprint requirements of the existing PCB layout.
