HIN207IB

Overview

The HIN207IB is a dual transmitter and dual receiver RS-232 interface circuit manufactured by Harris Semiconductor. It operates from a single +5V power supply, utilizing onboard charge pump voltage converters to generate the required positive and negative voltages for RS-232 signaling without external high-voltage sources. The device meets EIA RS-232E and V.28 specifications, supporting data rates up to 120kbit/s. It features true TTL/CMOS input compatibility and includes a low-power shutdown mode to conserve energy in battery-powered applications. The package designation 'I' indicates an industrial temperature range operation.

Feature Summary

• Single +5V power supply operation with integrated onboard charge pump voltage converters
• Low power shutdown mode designed to conserve energy in battery-powered systems
• True TTL/CMOS input compatibility with slew rate-limited outputs
• Receivers feature hysteresis to improve noise rejection capabilities

Applications

• Battery-powered portable equipment requiring RS-232 connectivity
• Industrial control systems operating within standard RS-232 environments
• Embedded systems with limited board space for external capacitors

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature range rating as defined in the official datasheet. Confirm the manufacturer origin, noting that Harris Semiconductor assets were acquired by Renesas Technology Corporation. Ensure the component version matches the original Harris documentation to guarantee parameter accuracy.

Selection Notes

Select this component when a single +5V supply is available but ±12V rails are not. The HIN207IB provides two drivers and two receivers, suitable for full-duplex communication. Compare against the HIN203 or HIN205 if zero external capacitors are strictly required, as those variants differ in external component needs.

Part Context

This part belongs to the HIN200-HIN213 family of +5V powered RS-232 transmitters and receivers. The family was designed to simplify interface design by eliminating the need for dual polarity power supplies. The HIN207IB specifically offers a dual-transmitter, dual-receiver configuration within this lineup.
