HIN207CB

Overview

The HIN207CB is a single transmitter and single receiver RS-232 interface circuit manufactured by Harris Corporation. It operates from a single +5V power supply, utilizing onboard charge pump voltage converters to generate the required ±10V supplies for RS-232 signaling. The device meets EIA RS-232E and V.28 specifications and supports data rates up to 120kbit/s. It features true TTL/CMOS input compatibility, slew rate-limited outputs with a maximum slew rate of 30V/µs, and receivers with ±30V input voltage range capability. The component includes 0.5V hysteresis for improved noise rejection and requires only 0.1µF or greater external capacitors.

Feature Summary

• Onboard charge pump voltage converters generate ±10V supplies from a single +5V source
• TTL/CMOS compatible inputs with three-state receiver outputs
• Integrated hysteresis in receivers to enhance noise immunity
• Slew rate-limited drivers to minimize electromagnetic interference

Applications

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

Procurement Notes

Verify the manufacturer designation carefully, as Harris Corporation's semiconductor assets were acquired by Renesas Technology Corp. Ensure the part number suffix matches the specific package and lead-free requirements. Confirm RoHS compliance status if applicable to the production environment. Cross-reference the datasheet revision date to ensure availability of updated electrical characteristics and handling instructions.

Selection Notes

Select this component when a single transmitter and receiver configuration is sufficient for the design. It is suitable for applications lacking dual ±12V power supplies, relying instead on a standard +5V rail. Consider the 120kbit/s data rate limit against system requirements. Evaluate the need for external capacitors, which must be 0.1µF or larger, against available board space constraints compared to capacitor-less alternatives in the same family.

Part Context

The HIN207CB belongs to the HIN200-HIN213 family of low-power RS-232 transceivers designed for +5V operation. This family provides various combinations of drivers and receivers to suit different interface needs. The HIN207 specifically offers one driver and one receiver, making it a compact solution for basic bidirectional serial communication links where full-duplex operation with minimal pin count is desired.

Replacement Considerations

HIN211CBZ-T is a confirmed substitute within the same functional family offering identical RS-232 capabilities and +5V operation.
