HIN241CB

Overview

The HIN241CB is a dual RS-232 transceiver manufactured by Harris Corporation, designed for communication applications requiring reliable data transmission. It operates from a single +5V power supply and incorporates internal charge pumps to generate the necessary positive and negative voltages for RS-232 signaling without external components. The device features two drivers and two receivers, providing full duplex communication capabilities. It is housed in a standard plastic DIP package suitable for through-hole mounting on printed circuit boards.

Feature Summary

• Integrated charge pump eliminates need for external voltage generation components
• Single +5V power supply operation simplifies system design
• Full duplex capability with dedicated driver and receiver channels

Applications

• Industrial control systems requiring serial communication
• Modem interface circuits
• Point-of-sale terminals

Procurement Notes

Verify the manufacturer origin as Harris Corporation or its successors, noting that Harris Semiconductor assets were acquired by Intersil and subsequently Renesas. Confirm the package type matches the required PCB footprint and ensure the operating temperature range meets the specific environmental requirements of the target application.

Selection Notes

Select this component when a dual-channel RS-232 solution is needed with minimal external bill of materials. It is appropriate for designs constrained by space or complexity where integrating charge pumps externally is undesirable. Ensure the data rate requirements align with the device specifications and that the +5V supply rail is stable within the specified tolerance.

Part Context

This part belongs to the family of RS-232 transceivers developed by Harris Semiconductor, which was a significant player in analog and mixed-signal integrated circuits before its acquisition. The company's semiconductor division eventually became part of Intersil, contributing to the lineage of modern Renesas Electronics products. This specific model represents a standard interface solution from that era of industrial electronics.

Replacement Considerations

Direct replacements may include the MAX232 series from Maxim Integrated or equivalent parts from Texas Instruments such as the SN75176 if differential signaling is acceptable. Verify pin compatibility and electrical characteristics against the original datasheet to ensure seamless integration into existing designs.
