HIN208CP

Overview

The HIN208CP is a CMOS RS-232 transmitter/receiver manufactured by Harris Corporation. It operates from a single +5V power supply and integrates onboard charge pump circuitry to generate the required ±10V output swings. The device provides two drivers and two receivers, meeting EIA RS-232E and V.28 specifications. It supports data rates up to 120kbit/s with a maximum slew rate of 30V/µs. The package is a 16-pin PDIP. Key electrical characteristics include a typical supply current of 5mA and receiver inputs capable of handling ±30V.

Feature Summary

• Integrates onboard voltage doubler and inverter to eliminate external high-voltage supplies
• Features TTL/CMOS compatible inputs and three-state outputs for system flexibility
• Includes 0.5V hysteresis on receivers to enhance noise rejection performance

Applications

• Computer serial communication ports
• Portable and laptop computer interfaces
• Peripheral connections such as printers and terminals
• Instrumentation systems requiring RS-232 connectivity

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix indicates the PDIP-28 package variant. Check for lead-free compliance status if required by project specifications. Ensure storage conditions adhere to moisture sensitivity levels defined in the datasheet.

Selection Notes

Select this component when a single +5V supply is available and ±12V rails are absent. It is suitable for applications requiring moderate data rates up to 120kbit/s. Consider alternative family members like the HIN203 if external capacitors must be minimized. Verify that the 30V input tolerance meets the interface requirements.

Part Context

This part belongs to the HIN200-HIN213 family of RS-232 interface circuits designed for low-power, single-supply operation. These devices were widely used in legacy computing and industrial control systems. The HIN208CP specifically offers a balanced configuration of two drivers and two receivers within a standard DIP package.

Replacement Considerations

Compatible substitutes include the MAX208CPE and the SP208E. Verify pin compatibility and electrical parameters such as drive strength and operating temperature range before substitution.
