ICL3232ECBNZ-T7A

Overview

The ICL3232ECBNZ-T7A is a full-duplex RS-232 transceiver manufactured by Renesas Electronics Corporation. It integrates two drivers and two receivers in a 16-pin SOIC package, supporting data rates up to 250 kbps. The device operates on a single 3V to 5.5V supply with a typical operating current of 1 mA. It features high ESD protection rated at 15 kV and functions within an industrial temperature range of -40°C to +85°C. The component complies with RoHS3 standards and has a Moisture Sensitivity Level (MSL) of 3.

Feature Summary

• High electrostatic discharge protection capability for robust signal integrity
• Low power consumption suitable for battery-operated systems
• Industrial-grade thermal stability for demanding environments

Applications

• RS-232 serial communication interfaces requiring high noise immunity
• Industrial control systems operating in electrically noisy environments
• Portable instrumentation powered by single-cell lithium batteries

Procurement Notes

Verify the specific suffix 'ECBNZ' against official Renesas documentation to confirm the enhanced ESD specifications and commercial temperature variant. Ensure the T7A tape-and-reel packaging matches assembly requirements. Cross-reference the manufacturer part number with authorized distributor databases to validate authenticity and traceability before procurement.

Selection Notes

Select this component when 15 kV ESD protection is mandatory for RS-232 links. Compare against standard ICL3232 variants if lower cost is acceptable without ESD enhancements. Confirm that the 16-SOIC footprint fits the PCB layout constraints. Verify that the 250 kbps speed meets the application's baud rate requirements.

Part Context

This part belongs to the ICL3232 family of RS-232 transceivers from Renesas. It shares functional similarities with the ICL3232IVZ-T7A but differs in packaging and environmental ratings. The EC series designation typically indicates enhanced ESD performance compared to standard industrial versions.

Replacement Considerations

ICL3232IVZ-T7A offers similar functionality but may lack the specific ESD rating. ICL3232IBNZ-T provides alternative packaging options. Verify pin compatibility and electrical parameters before substitution.
