HIN207CB-T

Overview

The HIN207CB-T is a single transmitter and single receiver RS-232 transceiver manufactured by Harris Corporation. It operates from a single +5V power supply, utilizing an onboard charge pump to generate the required positive and negative voltage levels for RS-232 signaling. The device meets EIA RS-232E and V.28 specifications, supporting data rates up to 120kbit/s. It features true TTL/CMOS input compatibility, slew-rate-limited outputs, and receivers with hysteresis for improved noise rejection. The component requires external 0.1µF capacitors for the charge pump operation.

Feature Summary

• Single +5V power supply operation with integrated onboard charge pump voltage converters
• Compliance with EIA RS-232E and V.28 interface specifications
• TTL/CMOS compatible inputs with slew-rate limited outputs to minimize electromagnetic interference
• High noise immunity receivers featuring input hysteresis and protection against ±30V input signals

Applications

• Serial communication interfaces in systems lacking dual polarity power supplies
• Industrial control equipment requiring robust RS-232 connectivity
• Embedded systems with space-constrained designs utilizing single-supply logic

Procurement Notes

Verify the manufacturer origin carefully, as Harris Corporation's semiconductor assets were acquired by Renesas Electronics. Ensure the specific suffix 'CB-T' corresponds to the correct tape-and-reel packaging and temperature grade intended for your assembly process. Cross-reference the part number with current Renesas documentation to confirm availability and final specification alignment.

Selection Notes

Select this component when a single +5V supply is available but RS-232 voltage levels are required. It is suitable for applications needing one transmitter and one receiver channel. Consider the HIN203 or HIN205 if external capacitors cannot be accommodated on the PCB layout. Verify that the 120kbit/s data rate meets the system timing requirements.

Part Context

The HIN207 is part of the HIN200-HIN213 family of +5V powered RS-232 transceivers. This family was designed to simplify interface design by eliminating the need for traditional ±12V power supplies. The HIN207 specifically provides a single driver and a single receiver, offering a compact solution for basic bidirectional serial communication needs.

Replacement Considerations

Renesas Electronics acquired Harris Semiconductor. Check for direct replacements within the Renesas HIN20x series. Other single-supply RS-232 transceivers from manufacturers like Maxim Integrated (now Analog Devices) or Texas Instruments may serve as functional alternatives if pinouts and electrical characteristics are verified.
