HIN202IBN

Overview

The HIN202IBN is a dual transmitter and receiver RS-232 interface circuit manufactured by Harris Corporation. It operates from a single +5V power supply, utilizing onboard charge pumps to generate the required ±10V levels for RS-232 signaling. The device meets EIA RS-232E and V.28 specifications with a data rate of 120kbit/s. Key electrical parameters include a typical supply current of 5mA and a shutdown current of 1µA. It features three-state TTL/CMOS compatible outputs, ±30V input voltage range on receivers, and ±10V output swing. The package is a 16-SOIC.

Feature Summary

• Onboard charge pump voltage converters eliminate the need for external ±12V supplies
• TTL/CMOS compatible inputs and outputs ensure broad logic compatibility
• Low power consumption with dedicated shutdown function for energy efficiency
• Robust noise rejection capabilities through defined hysteresis and input impedance

Applications

• Computer serial communication ports
• Portable and laptop computer interfaces
• Peripheral connections such as printers and terminals

Procurement Notes

Verify the manufacturer origin carefully, as Harris Corporation's semiconductor assets were acquired by Renesas Electronics. Ensure the specific suffix matches the required packaging and RoHS compliance status. Confirm that the onboard capacitors meet the minimum 0.1µF requirement specified in the datasheet for proper charge pump operation. Check for any pinout variations between original Harris and subsequent Renesas production runs.

Selection Notes

Select this component when a single +5V supply is available but RS-232 voltage levels are required without external high-voltage sources. It is suitable for applications where board space is limited compared to solutions requiring multiple external capacitors. Consider the 120kbit/s speed limit; higher baud rates may require alternative devices. Verify thermal performance within the -40°C to 85°C operating range for the specific enclosure environment.

Part Context

The HIN202IBN belongs to the HIN200-HIN213 family of RS-232 transceivers designed for low-power, single-supply applications. This family allows designers to choose between different numbers of drivers and receivers while maintaining consistent interface characteristics. The IBN suffix typically denotes an industrial temperature range and plastic SOIC packaging. These devices were widely used before the prevalence of USB and modern serial standards.

Replacement Considerations

Renesas Electronics offers direct replacements such as the HIN202IBZ and HIN202IBZT. These variants maintain functional compatibility but may differ in packaging options (tube vs. tape and reel) and RoHS compliance status. Verify that the replacement part number aligns with the specific manufacturing era and regulatory requirements of the target assembly.
