HIN238ECA

Overview

The HIN238ECA is a quad RS-232 transceiver manufactured by Harris Corporation, belonging to the HIN238 series. It integrates four drivers and four receivers for full-duplex communication at data rates up to 120 kb/s. The device operates on a single 4.5 V to 5.5 V power supply with a typical operating current of 15 mA. It utilizes external 1 µF capacitors for charge pumping. The component is housed in a 24-pin PDIP package and supports an industrial temperature range.

Feature Summary

• Integrates four independent drivers and four receivers for comprehensive serial communication interfaces.
• Utilizes a single 5 V power supply with internal charge pump circuitry requiring only external capacitors.
• Provides robust ESD protection exceeding industry standards for reliable operation in harsh environments.

Applications

• Industrial control systems requiring multiple serial ports
• Modem interface circuits
• Portable battery-operated instruments

Procurement Notes

Verify the manufacturer origin carefully as Harris Corporation's semiconductor assets were acquired by Intersil and subsequently Renesas. Confirm the specific suffix 'ECA' indicates the extended commercial or industrial temperature grade and PDIP packaging variant. Ensure compatibility with existing PCB footprints designed for 24-pin wide-body packages.

Selection Notes

Select this component when designing systems requiring four isolated RS-232 channels powered by a standard 5 V rail. Compare against the HIN238ECPZ for identical electrical performance but different packaging constraints. Consider the HIN238IBZ if surface-mount technology is preferred over through-hole installation for the same functional requirements.

Part Context

This part belongs to the HIN238 family of high-performance RS-232 transceivers originally developed by Harris Semiconductor. The series is characterized by low power consumption and compatibility with standard PC serial ports. The HIN238ECA specifically denotes the through-hole PDIP version intended for general-purpose industrial applications.
