ICL3232CBNZ-T

Overview

The ICL3232CBNZ-T is a low-power RS-232 transceiver manufactured by Renesas Electronics. It operates on a single power supply ranging from 3V to 5.5V and includes two drivers and two receivers for full-duplex communication. The device guarantees a minimum data rate of 250kbps and features an integrated charge pump requiring only four external 0.1µF capacitors. It provides 15kV ESD protection and offers shutdown current as low as 1µA. The component is housed in a 16-pin SOIC-Narrow package.

Feature Summary

• Integrated charge pump reduces external component count
• Automatic power-down mode extends battery life
• Receiver hysteresis improves noise immunity

Applications

• Portable computers and PDAs
• Battery-powered handheld devices
• Modems and printers

Procurement Notes

Verify the suffix 'T' indicates tape-and-reel packaging rather than tube. Confirm RoHS compliance status through official documentation. Ensure moisture sensitivity level handling procedures are followed during assembly to prevent damage.

Selection Notes

Select this part for applications requiring low standby current and minimal board space. Verify that the 250kbps speed meets system requirements. Check compatibility with 3V and 5V logic levels before integration.

Part Context

This component belongs to the ICL3232 series of RS-232 interface ICs. It serves as a low-power alternative to standard transceivers, designed specifically for portable electronics where energy efficiency is critical.

Replacement Considerations

Check for pin-compatible alternatives such as the MAX3232 or ST3232. Verify that substitute parts support the same 3V to 5.5V operating range and similar data rates.
