ICL3232ECBNZ-T

Overview

The ICL3232ECBNZ-T is a dual RS-232 transceiver manufactured by Renesas Electronics. It operates within a supply voltage range of 3.0 V to 5.5 V and supports data rates up to 250 kbps. The device features two drivers and two receivers, providing full-duplex communication capabilities. It incorporates ±15 kV ESD protection on all RS-232 lines and draws only 1 mA of supply current during active operation. Packaged in a 16-pin SOIC format, it complies with EIA/TIA-232 and V.28/V.24 specifications.

Feature Summary

• Integrated ±15 kV electrostatic discharge protection on transmit and receive lines
• Low power consumption with 1 mA operating current draw
• Compliance with EIA/TIA-232 and V.28/V.24 interface standards

Applications

• Industrial control systems requiring robust serial communication
• Portable instrumentation and battery-powered devices
• Computer peripheral interfaces

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the manufacturer designation as Renesas Electronics Corporation, noting historical Intersil origins. Ensure the component meets RoHS requirements for the intended market. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Selection Notes

Select this component for applications requiring dual-channel RS-232 connectivity with low standby power. The 250 kbps rate suits standard baud rates but may limit high-speed data transfer needs. The SOIC-16 package offers surface-mount convenience. Verify that the 3.0 V minimum supply voltage aligns with the system's power rails.

Part Context

This part belongs to the ICL3232 family of RS-232 transceivers. Variants such as ICL3232EIV-16Z-T differ primarily in package type, while ICL3232ECBNZ represents the tube-packaged version. The family shares identical electrical characteristics and functional pinouts across different packaging options.

Replacement Considerations

Direct substitutes include ICL3232EIV-16Z-T and ICL3232ECBNZ. These parts share identical electrical specifications and pin configurations. Differences are limited to packaging style (tape-and-reel versus tube) and potentially minor mechanical dimensions.
