ICL3232IBZ-T

Overview

The ICL3232IBZ-T is a dual RS-232 transceiver manufactured by Renesas Electronics Corporation, designed for full-duplex communication. 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 integrates two drivers and two receivers in a single package. It features ±15 kV electrostatic discharge (ESD) protection on all pins, ensuring robustness against electrical stress. The component is housed in a 16-pin SOIC surface-mount package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrated ±15 kV ESD protection on all signal pins for enhanced reliability
• Compliance with EIA/TIA-232 and V.28/V.24 interface specifications
• Low power consumption with typical operating current of 1 mA

Applications

• Industrial control systems requiring reliable serial communication
• Portable instrumentation and battery-powered devices
• Modems and fax machines utilizing standard RS-232 protocols

Procurement Notes

Verify the specific suffix 'IBZ' against official Renesas documentation to confirm the exact package variant and tape-and-reel configuration. Ensure that the procurement source provides valid RoHS compliance certificates and moisture sensitivity level ratings consistent with the datasheet requirements for this specific part number.

Selection Notes

Select this component when designing circuits that require dual-channel RS-232 connectivity with low standby current. It is suitable for applications where space constraints favor a 16-pin SOIC footprint over larger packages. Consider the 250 kbps speed limit when evaluating compatibility with high-speed serial peripherals or long cable runs.

Part Context

This part belongs to the ICL3232 family of RS-232 transceivers, which are widely used for converting TTL/CMOS logic levels to RS-232 voltages. The ICL3232 series is known for its ability to operate efficiently at lower supply voltages while maintaining compatibility with traditional RS-232 standards.

Replacement Considerations

Direct substitutes include the ICL3232EIBZ-T and ICL3232IVZ-T. Verify pinout compatibility and ensure that the alternative part meets the same voltage and temperature specifications before implementation.
