HIN208ACP

Overview

The HIN208ACP is a single RS-232 transmitter and receiver manufactured by Harris Corporation. It operates from a single +5V power supply, utilizing onboard charge pump voltage converters to generate the required ±10V levels for RS-232 signaling without external high-voltage sources. The device meets EIA RS-232E and V.28 specifications, supporting data rates up to 120 kbit/s. It features three-state TTL/CMOS compatible outputs and inputs with ±30V tolerance. Designed for low power consumption, it typically draws 5mA during operation and includes a shutdown mode reducing current to approximately 1µA. The component requires external 0.1µF capacitors for the charge pumps.

Feature Summary

• Onboard charge pump generates ±10V supplies from a single +5V source
• Meets EIA RS-232E and V.28 interface specifications
• Low power shutdown function minimizes standby current consumption
• TTL/CMOS compatible inputs and outputs with noise rejection hysteresis

Applications

• Computer serial communication ports
• Portable and laptop peripheral interfaces
• Printers and terminals requiring RS-232 connectivity
• Instrumentation systems with limited voltage rails

Procurement Notes

Verify the manufacturer origin, as Harris Corporation's semiconductor assets were acquired by Renesas Electronics. Confirm that the specific HIN208ACP part number corresponds to the original Harris datasheet specifications rather than a modern equivalent or pin-compatible substitute. Ensure the package type matches the required PCB footprint and check for RoHS compliance status if applicable to the procurement region.

Selection Notes

Select this component when an RS-232 interface is needed in a system powered exclusively by +5V, eliminating the need for dual-rail power supplies. It is suitable for applications requiring moderate data rates up to 120 kbit/s where board space allows for the necessary external capacitors. Consider alternatives if higher data rates or zero external capacitor designs are required.

Part Context

The HIN208ACP belongs to the HIN200-HIN213 family of RS-232 transceivers developed by Harris Corporation. This family was widely used in industrial and commercial electronics before the company's semiconductor division was acquired. The HIN208 specifically provides one driver and one receiver, offering a compact solution for basic serial communication needs compared to multi-channel variants in the same series.

Replacement Considerations

Renesas Electronics now produces the RH1208 and RH2208 series, which are direct successors to the Harris HIN200 series. Verify pin compatibility and electrical characteristics against the original Harris datasheet when substituting. Other generic RS-232 transceivers may require different external capacitor values or voltage supplies.
