HIN211IA

Overview

The HIN211IA is a quad line transceiver manufactured by Harris Corporation, designed for RS-232 communication applications. It integrates four drivers and five receivers within a single CMOS package. The device operates on a single 5V power supply and supports full-duplex data transmission with a maximum data rate of 230 kb/s. It features ±15kV electrostatic discharge (ESD) protection on all RS-232 lines, ensuring robust performance in industrial environments. The component is available in a 28-pin Plastic Dual Small Outline (PDSO28) package, also identified as SSOP-28, suitable for surface mount technology.

Feature Summary

• Integrates four independent drivers and five receivers for comprehensive serial communication capabilities.
• Provides high-level ESD protection rated at ±15kV to safeguard against static discharge events.
• Operates efficiently on a standard 5V single power supply with low quiescent current consumption.

Applications

• Industrial control systems requiring reliable serial data exchange
• Computer peripheral interfaces utilizing RS-232 standards
• Communication equipment needing robust signal transmission over noisy environments

Procurement Notes

Verify the manufacturer origin carefully, as the HIN211IA designation appears across multiple entities including Harris, Intersil, and Renesas. Confirm that the specific batch corresponds to the original Harris Corporation production if legacy compatibility is required. Check datasheet revisions to ensure pinout and electrical characteristics match the intended design specifications before finalizing procurement orders.

Selection Notes

Select this component when a quad driver/receiver configuration is necessary for complex RS-232 networks. Ensure the design accommodates the 28-pin PDSO/SSOP footprint and requires ±15kV ESD tolerance. Verify that the 5V supply voltage aligns with the system's power architecture and that the 230 kb/s data rate meets the application's throughput requirements without necessitating higher-speed alternatives.

Part Context

The HIN211IA belongs to the broader family of RS-232 interface integrated circuits originally developed by Harris Semiconductor. Following corporate acquisitions, the product lineage continued under Intersil and subsequently Renesas Electronics. This specific part number represents the quad transceiver variant, distinct from dual or single-channel counterparts within the same functional series.

Replacement Considerations

Direct substitutes include the HIN211EIAZ-T and other variants within the HIN211 series produced by Renesas or Intersil. These components share identical functional descriptions and pinouts. Verify package compatibility between PDSO28 and SSOP-28 forms during replacement planning.
