HIN232ECBZ-T

Overview

The HIN232ECBZ-T is a high-speed RS-232 transmitter/receiver interface circuit manufactured by Renesas Electronics. It meets all EIA RS-232E and V.28 specifications, designed for applications lacking ±12V power supplies. The device operates on a single +5V supply, utilizing onboard charge pump voltage converters to generate the necessary internal voltages. Key electrical parameters include a data rate of 230 kbit/s, a supply voltage range of 4.5V to 5.5V, and an operating current of 15 mA. It features ±15kV ESD protection on transmitter outputs and receiver inputs, ensuring robust performance in sensitive environments.

Feature Summary

• Integrated onboard charge pump voltage converters eliminate the need for external ±12V power supplies.
• Transmitter outputs and receiver inputs are protected against electrostatic discharge up to ±15kV.
• Supports high-speed data transmission rates suitable for ISDN and modem applications.
• Receivers incorporate hysteresis to significantly improve noise rejection capabilities.

Applications

• High-speed RS-232 communications ports in computer systems
• Portable, mainframe, and laptop computer interfaces
• Peripheral connections for printers and terminals
• Instrumentation and UPS system serial communication

Procurement Notes

Verify the specific suffix 'CBZ-T' against official Renesas documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with SOIC-16-300mil footprint requirements during PCB layout. Confirm RoHS compliance status through manufacturer datasheets prior to procurement.

Selection Notes

Select this component when a single +5V supply is available but ±12V rails are absent. The HIN232ECBZ-T is appropriate for designs requiring 2 drivers and 2 receivers with high-speed data rates. Consider the SOIC-16 package constraints and thermal characteristics relative to the application's environmental conditions.

Part Context

This part belongs to the HIN232E family of RS-232 transmitters and receivers. The family shares common architecture including onboard charge pumps and ESD protection. Variants within the series differ primarily in driver/receiver counts and shutdown modes, while maintaining core RS-232E compliance and single-supply operation.

Replacement Considerations

Direct substitutes within the same family include HIN232E variants with identical pinouts and functionality. Verify that alternative parts maintain the 230 kbit/s data rate and ±15kV ESD protection levels required for the specific application environment.
