HIN207IP

Overview

The HIN207IP is a single RS-232 transmitter and receiver interface circuit manufactured by Harris Corporation. It operates from a single +5V power supply and utilizes onboard charge pump voltage converters to generate the required positive and negative voltages for RS-232 signaling, eliminating the need for external dual supplies. The device features true TTL/CMOS input compatibility and includes slew-rate-limited outputs to minimize electromagnetic interference. It meets EIA RS-232E and V.28 specifications and requires only 0.1µF external capacitors for the internal charge pumps.

Feature Summary

• Single +5V power supply operation with integrated onboard charge pump voltage converters
• Compliance with EIA RS-232E and V.28 interface specifications
• True TTL/CMOS input compatibility for direct logic interfacing
• Slew-rate-limited output drivers to reduce signal ringing and noise

Applications

• Serial communication interfaces in systems lacking ±12V power rails
• Industrial control equipment requiring robust RS-232 connectivity
• Embedded systems with space constraints utilizing minimal external components

Procurement Notes

Verify the manufacturer origin, as Harris Semiconductor assets were acquired by Intersil and subsequently Renesas. Confirm the specific package type and suffix (e.g., IP for PDIP) matches the design requirements. Check for RoHS compliance status if modern environmental standards are mandatory for the assembly process.

Selection Notes

Select this component when a single +5V supply is available but RS-232 levels are required. It is suitable for applications needing one transmitter and one receiver channel. Ensure the data rate requirements do not exceed the specified limits and that the load capacitance is within the driver capabilities. Consider pinout compatibility if replacing legacy designs.

Part Context

The HIN207IP belongs to the HIN200-HIN213 family of +5V powered RS-232 transceivers. This family was designed to simplify interface circuits by removing the need for complex dual-voltage power supplies. The HIN207 variant specifically provides a single driver and a single receiver, offering a compact solution for basic serial communication needs.

Replacement Considerations

Direct replacements may include the MAX207 or MAX232 series from Maxim Integrated (now Analog Devices). Verify pin-to-pin compatibility and electrical parameter alignment, particularly regarding drive strength and operating temperature range, before substituting.
