ICL3232EIBZ-T

Overview

The ICL3232EIBZ-T is a triple driver, five receiver RS-232 transceiver manufactured by Renesas Electronics. It operates on a single power supply ranging from 3.0V to 5.5V and complies with EIA/TIA-232 and V.28/V.24 standards. The device integrates an efficient charge pump requiring only four external 0.1µF capacitors. It guarantees a minimum data rate of 250kbps and features 15kV ESD protection per the human body model. The part utilizes SOIC-16 surface-mount packaging.

Feature Summary

• Integrates three drivers and five receivers for complete serial port functionality
• Includes an always-active non-inverting receiver for system wake-up capabilities
• Features automatic power-down mode to minimize standby current consumption
• Provides receiver hysteresis to enhance noise immunity

Applications

• Battery-powered handheld and portable devices
• Laptop computers and PDAs
• Modems and peripheral equipment
• Digital cameras and cellular phones

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices as this series may have limited availability. Ensure proper handling procedures are followed due to electrostatic sensitivity.

Selection Notes

Select this component when a full RS-232 interface is required in space-constrained designs. It serves as a low-power upgrade compatible with HIN232/ICL232 pinouts. Verify that the application supports the 3.0V to 5.5V operating range and requires the specific driver/receiver count provided.

Part Context

This device belongs to the ICL3232 family of RS-232 interface ICs designed for low-voltage operation. It replaces older generation transceivers by offering reduced power consumption while maintaining standard compatibility. The suffix indicates tape-and-reel packaging for automated assembly processes.

Replacement Considerations

Direct replacements include ICL3232CA, ICL3232CBNZ, and ICL3232IBNZ. These variants share identical electrical specifications and pin configurations. Verify package type and temperature grade before substitution.
