HIN238ACA

Overview

The HIN238ACA is a line transceiver manufactured by Harris Corporation, designed for RS-232 communication interfaces. It integrates four drivers and four receivers within a single CMOS package. The device operates on a single 5 V power supply and supports data rates up to 120 kbps. It features true driver outputs that comply with EIA/TIA-232-F and ITU-T V.28 standards. The component includes internal charge pumps to generate the necessary positive and negative voltages from the single supply. It is housed in a 24-pin PDIP package and is rated for an operating temperature range of 0 °C to +70 °C.

Feature Summary

• Integrates four independent drivers and four independent receivers for multi-channel serial communication
• Utilizes internal charge pump circuitry to eliminate the need for external dual-voltage power supplies
• Provides true output polarity for drivers, ensuring signal levels match standard RS-232 voltage requirements

Applications

• Industrial equipment requiring serial data transmission
• Modem interface circuits
• Printers and peripheral connections
• Communications equipment utilizing RS-232 protocols

Procurement Notes

Verify the manufacturer designation, as Harris Corporation's semiconductor assets were acquired by Renesas Electronics. Confirm the specific package variant matches the required pinout and thermal characteristics. Ensure the component meets the intended environmental temperature specifications for the target application environment.

Selection Notes

Select this component when a design requires multiple RS-232 channels without external voltage generation. Compare against alternatives based on the number of drivers and receivers needed. Consider the PDIP package constraints if surface mount space is limited. Verify compatibility with the system's 5 V logic levels.

Part Context

This part belongs to the HIN238 series of RS-232 transceivers. The series typically offers variations in package types and temperature ranges. The ACA suffix generally denotes the commercial temperature grade and plastic packaging. This family simplifies interface design by consolidating signal conditioning and voltage translation into a single integrated circuit.

Replacement Considerations

Check for equivalents such as the MAX238 or SP238 series. Verify that substitute parts maintain the same 4-driver/4-receiver configuration and PDIP-24 footprint. Ensure the replacement supports the 120 kbps data rate and 5 V single-supply operation.
