HIN206ECA

Overview

The HIN206ECA is a single RS-232 transmitter and receiver interface circuit manufactured by Harris Corporation. 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. The device meets EIA high-speed RS-232E and V.28 specifications. Key electrical parameters include a data rate of up to 120 kbps, ±15kV ESD protection on drivers and receivers, and a shutdown mode that reduces supply current to 15 µA. It features true TTL/CMOS input compatibility and slew-rate-limited outputs.

Feature Summary

• Single-supply operation with integrated charge pumps eliminating the need for external dual-voltage sources
• High electrostatic discharge (ESD) protection rated at ±15kV on both transmitter outputs and receiver inputs
• Low-power shutdown mode designed to conserve energy in battery-powered applications
• True TTL and CMOS logic input compatibility ensuring direct interfacing with standard digital logic families

Applications

• Portable computers and laptop peripheral connections
• Industrial instrumentation requiring robust serial communication
• Uninterruptible Power Supply (UPS) monitoring systems
• ISDN terminal adaptors and high-speed modem interfaces

Procurement Notes

Verify the specific suffix 'ECA' against the manufacturer's official documentation to confirm temperature range and package type. Ensure the component source matches the original Harris Corporation or authorized successor lineage to guarantee parameter accuracy. Cross-reference the datasheet revision date with your project requirements to validate compliance with current EIA standards.

Selection Notes

Select this component when a single +5V supply is available but traditional RS-232 levels are required without external DC-DC converters. The HIN206ECA is suitable for designs prioritizing low standby power through its shutdown feature. Compare it against other family members like the HIN202E or HIN232E if different pin configurations or driver/receiver counts are needed for the specific board layout constraints.

Part Context

The HIN206ECA belongs to the HIN20xE family of RS-232 transceivers developed by Harris Semiconductor. This family was engineered to simplify serial communication interface design by integrating charge pumps directly onto the silicon die. The part serves as a bridge between TTL/CMOS logic levels and RS-232 voltage standards, widely used in industrial and commercial equipment before being absorbed into Intersil and subsequently Renesas Technology.

Replacement Considerations

Compatible substitutes within the same functional family include the HIN202E, HIN207E, and HIN208E. These parts share similar electrical characteristics and pinouts but may differ in driver/receiver configuration. Verify pin compatibility and thermal performance before substitution. Modern equivalents from manufacturers like Maxim Integrated or Texas Instruments should be evaluated for pin-to-pin compatibility and updated ESD ratings.
