HIN232IP

Overview

The HIN232IP is a single-function line transceiver manufactured by Harris Corporation, designed for RS-232 communication applications. It integrates two drivers and two receivers within a CMOS process, housed in a 16-pin Plastic Dual Small Outline (PDSO) package. The device complies with EIA-232-E, V.24, and V.28 standards. Key electrical characteristics include an inverted output polarity and a minimum output voltage swing of 10 V. The input stage utilizes Schmitt trigger characteristics to enhance noise immunity. The component operates within a temperature range of -40 °C to +70 °C, with specific maximum ratings including a high-level input current of 0.00004 A and a maximum low-level output current of 0.0032 A.

Feature Summary

• Integrates dual drivers and dual receivers for full-duplex serial communication
• CMOS technology ensures low power consumption relative to older bipolar implementations
• Schmitt trigger inputs provide improved noise rejection on the receive lines

Applications

• Industrial control systems requiring RS-232 connectivity
• Embedded data acquisition modules
• Legacy computer peripheral interfacing

Procurement Notes

Verify the RoHS compliance status carefully, as official documentation indicates this specific part number is not compliant. Confirm the package variant matches the required PDSO16 footprint during sourcing. Ensure the supplier provides traceable origin from Harris Corporation or authorized distributors to avoid counterfeit components. Check for any specific ordering suffixes that might alter temperature grades or packaging formats.

Selection Notes

Select this component when a CMOS-based RS-232 transceiver is required for cost-sensitive designs. The 16-pin PDSO package offers a compact solution for space-constrained PCB layouts. Consider the Schmitt trigger inputs if the application environment has significant signal noise. Verify that the 10 V output swing meets the voltage requirements of the connected DTE or DCE equipment.

Part Context

The HIN232 series represents Harris Corporation's contribution to the standard RS-232 interface market, competing with similar offerings from manufacturers like Maxim Integrated. The 'HIN' prefix typically denotes Harris Semiconductor products. This specific model serves as a foundational component for serial communication interfaces in industrial and commercial electronics before the widespread adoption of USB and Ethernet alternatives.

Replacement Considerations

Direct pin-to-pin replacements may include the MAX232 family or the TRS232 series. Verify that substitute components maintain the same 16-pin PDSO/SSOP footprint and compatible supply voltage ranges. Ensure the replacement also supports the required EIA-232-E standard and offers comparable drive strength.
