HIN203ECB

Overview

The HIN203ECB is a single RS-232 transmitter and receiver manufactured by Harris Corporation. It operates from a single +5V power supply, utilizing an onboard charge pump to generate the required ±10V internal voltages without external capacitors. The device supports data rates up to 120kbit/s and features three-state TTL/CMOS compatible outputs. It meets EIA RS-232E and V.28 specifications, offering low power consumption with typical active current of 5mA and shutdown current of 1µA.

Feature Summary

• Integrated charge pump eliminates need for external capacitors
• Single +5V power supply operation
• TTL/CMOS compatible inputs and outputs

Applications

• Computer serial ports
• Portable and laptop systems
• Printers and terminals

Procurement Notes

Verify manufacturer authenticity as Harris Corporation assets were acquired. Confirm package type matches CB (Ceramic DIP). Check RoHS compliance status against original manufacturing dates. Ensure datasheet version aligns with specific revision requirements for your design.

Selection Notes

Select this component when board space is critical due to the absence of external capacitors. Compare against HIN202IBN if external capacitors are acceptable. Verify voltage levels match system logic requirements. Consider availability constraints given the component's age.

Part Context

Part of the HIN200-HIN213 family of RS-232 interface circuits designed for applications where ±12V supplies are unavailable. These devices simplify circuit design by integrating voltage conversion on-chip.

Replacement Considerations

Maxim MAX232 series offers similar functionality. ST L9637 provides comparable single-supply operation. Verify pin compatibility before substitution.
