HIN232ACBNZ

Overview

The HIN232ACBNZ is a high-speed RS-232 transmitter/receiver interface circuit manufactured by Renesas Electronics Corporation. It meets EIA RS-232E and V.28 specifications, operating on a single +5V power supply with onboard charge pump voltage converters generating ±10V supplies. The device features a data rate of 230kbit/s, requiring only 0.1µF external capacitors. It includes multiple drivers with ±10V output swing and three receivers with ±30V input range. Key electrical parameters include a typical supply current of 5mA, 300Ω power-off source impedance, and 3kΩ to 7kΩ receiver input impedance. The component operates within a temperature range of 0°C to +70°C and provides ±15kV ESD protection.

Feature Summary

• Onboard voltage doubler and inverter generate required ±10V supplies from a single +5V source, eliminating the need for external dual-voltage rails.
• Integrated ±15kV electrostatic discharge (ESD) protection on bus pins enhances reliability in sensitive environments.
• Receiver inputs feature hysteresis to significantly improve noise rejection capabilities.
• Drivers provide true TTL/CMOS input compatibility with slew-rate-limited outputs to minimize electromagnetic interference.

Applications

• High-speed RS-232 communications ports in computer systems
• Portable, mainframe, and laptop computer interfaces
• Peripheral connections for printers and terminals
• Instrumentation and uninterruptible power supply (UPS) systems

Procurement Notes

Verify the specific suffix 'CBNZ' against the manufacturer's official documentation to confirm package type, lead finish, and environmental compliance status. Ensure the ordering information matches the exact RoHS and Pb-Free requirements specified in the latest datasheet revision. Cross-reference the part number with authorized distributors to confirm active status and availability constraints.

Selection Notes

Select this component when a single +5V supply is available but ±12V rails are absent. It is suitable for applications requiring high data rates up to 230kbit/s. Consider the 0.1µF minimum capacitor requirement for the charge pump. Verify that the 0°C to +70°C commercial temperature range meets the operational environment needs before finalizing the design.

Part Context

The HIN232ACBNZ belongs to the HIN232E family of RS-232 transceivers designed for high-speed communication. This family shares common architecture features such as onboard charge pumps and ESD protection. The 'A' variant typically denotes specific performance or packaging variations within the series. It serves as a direct interface solution between microprocessors and serial communication ports.

Replacement Considerations

Direct substitutes within the same family include HIN232ACZNZ and HIN232ECBNZ. Verify pinout compatibility and electrical parameter equivalence, particularly regarding data rate and ESD ratings, before substituting. Consult the manufacturer's selection guide for alternative packages or extended temperature ranges if necessary.
