HIN239IP

Overview

The HIN239IP is a dual line transceiver manufactured by Harris Corporation, designed for RS-232 communication applications. It integrates two drivers and two receivers within a single CMOS package. The device operates from a single +5V power supply and includes internal charge pumps to generate the necessary positive and negative voltages for RS-232 signal levels. It features a wide operating temperature range and is housed in a standard plastic DIP package with 16 pins.

Feature Summary

• Integrates dual drivers and dual receivers for complete RS-232 interface functionality
• Operates from a single +5V power supply using internal charge pumps
• Provides EIA/TIA-232-E compliant output voltage levels
• Features low supply current consumption suitable for battery-powered systems

Applications

• Portable computers and laptop interfaces
• Modems and communication equipment
• Industrial control systems requiring RS-232 connectivity
• Point-of-sale (POS) terminals

Procurement Notes

Verify the manufacturer origin as Harris Corporation or its successors, noting that Harris Semiconductor assets were acquired by Dialog Semiconductor and subsequently integrated into Renesas Electronics. Confirm the package type is a 16-pin DIP (JEDEC MS-001) and check for any suffix variations indicating temperature range or tape-and-reel packaging. Ensure the component meets current RoHS directives if required for the specific application environment.

Selection Notes

Select this component when a dual-channel RS-232 transceiver is needed with low power consumption and single-supply operation. Compare against similar devices like the MAX232 or SP232E regarding pin compatibility and drive strength. Consider the operating temperature range (-40°C to +85°C) for industrial environments. Verify that the input thresholds are compatible with the logic family of the connected microcontroller or processor.

Part Context

The HIN239 series belongs to the Harris Semiconductor line of interface ICs, which were widely used before the company's semiconductor division was sold. These components are part of a broader family of RS-232 transceivers that simplified the design of serial communication ports by eliminating external capacitors for charge pump circuits. The IP suffix typically denotes the plastic DIP package variant.

Replacement Considerations

Direct pin-compatible replacements include the MAX239 (Maxim Integrated), SP239E (Exar/Renesas), and ST239 (STMicroelectronics). When substituting, verify that the replacement device maintains the same driver/receiver configuration and operates within the same voltage and temperature specifications. Check for any differences in input threshold voltages or output drive capabilities.
