HIN211CA

Overview

The HIN211CA is a quad line transceiver manufactured by Harris Corporation, designed for RS-232 communication. It operates on a single +5V power supply and features onboard charge pump voltage converters to generate the required ±10V supplies. The device includes four drivers and five receivers, supporting full-duplex data transmission at rates up to 120 kbit/s. It meets EIA RS-232E and V.28 specifications. Key electrical parameters include a maximum supply voltage of 5.5V, minimum of 4.5V, and operating current of 20 mA. It offers ±15kV ESD protection and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Onboard charge pump voltage converters eliminate the need for external dual-voltage supplies.
• Integrated ±15kV ESD protection enhances reliability in harsh environments.
• Low power shutdown mode conserves energy in battery-powered applications.
• True TTL/CMOS input compatibility simplifies interface with digital logic.

Applications

• Industrial control systems requiring robust serial communication.
• Battery-operated portable devices needing low power consumption.
• Data acquisition equipment interfacing with PC-based measurement systems.

Procurement Notes

Verify the manufacturer origin, as Harris Corporation's semiconductor assets were acquired by Intersil and subsequently Renesas Electronics. Ensure the specific suffix matches the required package type (e.g., SSOP-28) and temperature grade. Confirm RoHS compliance status if required for modern manufacturing standards. Cross-reference part numbers with current Renesas or Intersil catalogs to ensure availability and correct documentation access.

Selection Notes

Select this component when a quad driver/five receiver configuration is needed for RS-232 interfaces. It is suitable for designs constrained by space due to minimal external capacitor requirements. Consider the 120 kbit/s data rate limit for high-speed applications. Verify that the single +5V supply constraint aligns with the system power architecture. Check for equivalent parts from Renesas if Harris-branded units are obsolete.

Part Context

The HIN211CA belongs to the HIN200-HIN213 family of RS-232 transmitters/receivers developed by Harris Semiconductor. This family was widely used before the company's acquisition by Intersil. The HIN211 variant specifically provides a balanced mix of drivers and receivers. Understanding this lineage helps in sourcing replacements from Renesas, which now holds the rights to these legacy designs.
