ICL3232EIBNZ-T

Overview

The ICL3232EIBNZ-T is a dual driver, dual receiver RS-232 transceiver manufactured by Renesas Electronics. It operates within a supply voltage range of 3 V to 5.5 V and supports full-duplex communication at data rates up to 250 kb/s. The device features 15 kV ESD protection and draws only 1 mA of operating power current. It is housed in a 16-pin SOIC package and functions across an industrial temperature range from -40 °C to +85 °C.

Feature Summary

• Integrated charge pump requiring only four external capacitors for operation
• High electrostatic discharge protection rated at 15 kV
• Low standby power consumption with automatic shutdown capability

Applications

• Portable computers and notebook systems
• Battery-powered handheld devices
• Modems and peripheral equipment connections

Procurement Notes

Verify the specific suffix 'T' indicates reel packaging when sourcing. Confirm the manufacturer designation as Renesas or Intersil depending on the production era. Ensure the component meets RoHS standards if required by the assembly process. Check moisture sensitivity levels prior to soldering to prevent damage during reflow.

Selection Notes

Select this component for designs requiring RS-232 compatibility with low-voltage microcontrollers. It serves as a direct replacement for legacy Intersil parts in existing layouts. Verify that the system requires two drivers and two receivers rather than higher channel counts. Ensure the PCB layout accommodates the necessary small-value capacitors for the internal charge pump.

Part Context

This part belongs to the ICL3232 series of low-power RS-232 transceivers. The family is designed for portable applications where power efficiency is critical. The device maintains compatibility with standard RS-232 protocols while operating from single 3 V or 5 V supplies. It represents a transition point between older Intersil branding and modern Renesas Electronics product lines.

Replacement Considerations

The ICL3232CBNZ is a compatible alternative within the same functional family. Both devices share identical pinouts and electrical specifications for dual-channel RS-232 communication.
