ICL3232ECBNZ

Overview

The ICL3232ECBNZ is a dual RS-232 transceiver manufactured by Renesas Electronics Corporation, housed in a 16-pin SOIC package. It operates on a single power supply ranging from +3V to +5.5V and supports data rates up to 250kbps while meeting EIA/TIA-232 and V.28/V.24 specifications. The device features an integrated charge pump requiring only four external 0.1µF capacitors. Key electrical parameters include a maximum operating current of 1mA, ±15kV ESD protection, and a receiver hysteresis of 300mV. It functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Integrated charge pump reduces external component count by requiring only four small capacitors
• Provides ±15kV ESD protection for enhanced signal integrity and reliability
• Features receiver hysteresis to improve noise immunity in harsh environments
• Low standby power consumption with 1µA shutdown current

Applications

• Personal Digital Assistants (PDAs) and handheld devices
• Laptop computers and portable systems
• Modems and peripheral equipment connections
• Digital cameras and cellular/mobile phones

Procurement Notes

Verify the specific suffix 'CBNZ' against the manufacturer's official documentation to confirm RoHS compliance status and lead-free material composition. Ensure the procurement channel provides valid traceability records. Confirm that the 16-SOIC package dimensions match the design footprint requirements before finalizing orders.

Selection Notes

Select this component when designing systems requiring full-duplex RS-232 communication with low power constraints. It is suitable for 3.0V to 5.5V logic interfaces. Consider the 250kbps speed limit and commercial temperature range during selection. Verify compatibility with existing charge pump capacitor values to ensure stable operation without additional external components.

Part Context

This part belongs to the ICL3232 series of RS-232 transmitters and receivers designed for low-power applications. The series includes variants such as ICL3232EIV-16Z-T and ICL3232CBNZ, offering similar functional capabilities across different packaging options like TSSOP and SOIC. These devices are engineered to replace older high-voltage RS-232 solutions in modern portable electronics.
