HIN211CA-TS2473

Overview

The HIN211CA-TS2473 is a quad line transceiver manufactured by Harris Corporation, designed for RS-232 communication interfaces. It operates on a single +5V power supply and integrates onboard charge pump voltage converters to generate the necessary positive and negative voltages from the input source. The device features four drivers and five receivers, ensuring compatibility with TTL/CMOS logic levels. It meets EIA RS-232E and V.28 specifications, providing reliable data transmission at rates up to 120kbit/s. The package type is identified as PDSO28 or SSOP-28.

Feature Summary

• Integrates onboard voltage doubler and charge pump converters to eliminate external high-voltage supplies
• Features true TTL/CMOS input compatibility for direct interface with digital logic circuits
• Includes slew rate-limited outputs to minimize electromagnetic interference during signal transitions
• Provides low power shutdown mode to conserve energy in battery-powered applications

Applications

• Battery-powered portable equipment requiring efficient power management
• Industrial control systems utilizing RS-232 serial communication protocols
• Embedded systems where ±12V power rails are unavailable
• Data acquisition modules interfacing microcontrollers with serial peripherals

Procurement Notes

Verify the specific suffix TS2473 against official Harris or Renesas documentation to confirm tape-and-reel packaging details. Ensure the component matches the original Harris Corporation manufacturing lineage, as production rights may have transferred. Cross-reference the date code and lot number with authorized distributors to prevent counterfeit components. Confirm that the PDSO28 or SSOP-28 package variant aligns with your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when designing systems that require quad RS-232 channels without external charge pumps. It is suitable for applications needing shutdown modes to extend battery life. Compare it against the HIN211E series if higher electrostatic discharge protection ratings are required. Ensure the design accommodates the 0.1µF external capacitors needed for the internal voltage converters. Verify that the 120kbit/s data rate meets the system's throughput requirements.

Part Context

This part belongs to the HIN200-HIN213 family of +5V powered RS-232 transmitters and receivers. The family was originally developed by Harris Semiconductor, which later became part of Intersil and subsequently Renesas Electronics. These devices were widely used in legacy industrial and commercial equipment. The HIN211 specifically offers a combination of four drivers and five receivers, making it versatile for complex serial bus topologies.
