HIN203ECP

Overview

The HIN203ECP is a dual RS-232 transceiver manufactured by Harris Corporation, designed for low-power applications. It operates from a single +5V supply and incorporates charge pump circuitry to generate the necessary positive and negative voltages for RS-232 signal levels without requiring external inductors or transformers. The device features two drivers and two receivers, providing full compliance with EIA/TIA-232-E standards. It includes protection circuits on both inputs and outputs to safeguard against electrostatic discharge and other transient events. The component is housed in a standard 16-pin DIP package, suitable for through-hole mounting on printed circuit boards.

Feature Summary

• Integrated charge pump eliminates need for external inductors or transformers
• Single +5V power supply operation reduces system complexity
• Built-in protection against electrostatic discharge on I/O lines

Applications

• Portable battery-powered equipment requiring RS-232 communication
• Industrial control systems with limited power budgets
• Embedded data acquisition modules

Procurement Notes

Verify the manufacturer marking and date code on the physical component to ensure authenticity. Confirm that the suffix 'ECP' corresponds to the specific lead frame and packaging variant required for your assembly process. Check for any obsolescence notices from Harris Corporation or its successors before finalizing procurement plans.

Selection Notes

Select this component when a dual-channel RS-232 interface is needed with minimal external passive components. Ensure the design environment supports single-supply operation. Verify that the input voltage range of the connected microcontroller or logic device is compatible with the receiver output levels generated by this transceiver under load.

Part Context

This part belongs to the family of low-power RS-232 transceivers developed during the era of portable computing growth. Harris Corporation was a significant supplier of such interface components before various corporate acquisitions and restructuring in the semiconductor industry affected brand continuity.

Replacement Considerations

Direct pin-compatible replacements may include the MAX232 series from Maxim Integrated or equivalent parts from Texas Instruments. Verify electrical specifications such as drive current and propagation delay to ensure functional equivalence in the specific application circuit.
