HIN202EIP

Overview

The HIN202EIP is a dual transmitter and receiver RS-232 interface circuit manufactured by Harris Corporation. It operates on a single +5V power supply, utilizing onboard charge pumps to generate the required ±10V levels from external 0.1µF capacitors. The device supports data rates up to 230 kb/s and features full-duplex communication with two drivers and two receivers. It includes ±15kV ESD protection on inputs and outputs, ensuring robust performance in electrically noisy environments while maintaining compatibility with TTL and CMOS logic levels.

Feature Summary

• Integrated charge pump voltage converters eliminate the need for external ±12V power supplies
• High electrostatic discharge protection rated at ±15kV on all signal lines
• Receiver inputs feature hysteresis to enhance noise rejection capabilities
• Outputs maintain low source impedance during power-off states for bus sharing

Applications

• Portable computers and laptop serial port implementations
• Industrial instrumentation requiring reliable RS-232 connectivity
• Uninterruptible Power Supply (UPS) management interfaces
• ISDN terminal adaptors and high-speed modem connections

Procurement Notes

Verify the specific suffix 'IP' against official Harris or Intersil documentation to confirm package type and temperature range. Ensure the component matches the SOIC-Wide-16 footprint if surface mount installation is required. Cross-reference manufacturer part numbers as ownership transferred from Harris to Intersil and subsequently to Renesas Electronics.

Selection Notes

Select this component when a single +5V supply is available but standard RS-232 voltage levels are needed without external negative voltage generators. The ESD-protected variant is suitable for exposed ports. Verify that the 230 kb/s data rate meets system requirements, as older non-E versions may have lower speed specifications.

Part Context

This part belongs to the HIN202E family of RS-232 transceivers designed to replace legacy circuits requiring dual polarity supplies. The 'E' designation indicates enhanced features including higher data rates and ESD protection compared to earlier iterations. Harris Corporation originally developed this line before its semiconductor division was acquired by Intersil.

Replacement Considerations

HIN202EIBZ-T is a confirmed equivalent from Renesas/Intersil offering identical functionality in a compatible SOIC-Wide-16 package.
