HIN232EIBNZ-T

Overview

The HIN232EIBNZ-T is a high-speed RS-232 transceiver manufactured by Renesas Electronics. It operates on a single +5V power supply and includes onboard charge pump circuitry to generate the required ±10V levels, eliminating the need for external dual supplies. The device features two drivers and two receivers, supporting data rates up to 230 kbps. It provides ±15kV electrostatic discharge (ESD) protection on all RS-232 pins, compliant with IEC61000 standards. The component is housed in a 16-pin SOIC package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated ESD protection rated at ±15kV on transmitter outputs and receiver inputs
• Single +5V power supply operation with internal voltage conversion
• High-speed data transmission capability up to 230 kbps
• TTL/CMOS compatible inputs with hysteresis for improved noise rejection

Applications

• ISDN terminal adaptors requiring high-speed communication
• High-speed modem interfaces
• Portable computer and laptop serial ports
• Industrial instrumentation and UPS systems

Procurement Notes

Verify the manufacturer date code and lot number against the supplier's certificate of conformity to ensure authenticity. Confirm that the packaging integrity remains sealed to prevent moisture absorption, as the component exhibits humidity sensitivity. Cross-reference the part marking with official Renesas documentation to validate the specific suffix and package variant before finalizing procurement orders.

Selection Notes

Select this component when designing systems limited to a single +5V power rail where traditional ±12V supplies are unavailable. It is suitable for applications demanding robust ESD immunity and high data rates. Ensure the design accommodates the required 0.1µF or larger external capacitors for the onboard charge pump. Verify that the 16-SOIC package dimensions fit the available PCB footprint constraints.

Part Context

This part belongs to the HIN232E family of RS-232 transmitters and receivers from Renesas. The family shares common architectural features, including high-speed performance and ESD protection, but varies in the number of drivers and receivers. The HIN232E specifically provides a 2-driver, 2-receiver configuration, distinguishing it from variants like the HIN202E or HIN213E which offer different channel counts or shutdown capabilities.

Replacement Considerations

Direct replacements include other members of the HIN232E family such as the HIN232EIBZ, provided pin compatibility is confirmed. Alternative interface ICs from other manufacturers may require schematic modifications due to differences in charge pump requirements or pinout configurations.
