HIN238ACB

Overview

The HIN238ACB is a quad transceiver manufactured by Harris Corporation, designed for RS-232 communication applications. It features a 24-pin PDIP package and operates on a single 5 V power supply. The device includes four transmitters and four receivers, supporting data rates up to 120 kbps. It is rated for an operating temperature range of 0 °C to +70 °C. Physical dimensions are approximately 32.51 mm in length, 7.11 mm in width, and 4.95 mm in height.

Feature Summary

• Provides four independent transmitter and receiver channels for RS-232 signaling
• Operates from a single 5 V power supply with CMOS/TTL logic compatibility
• Includes internal charge pumps to generate positive and negative voltages
• Designed for through-hole mounting in standard industrial environments

Applications

• Industrial control systems requiring serial communication
• Computer peripheral interfaces using RS-232 standards
• Embedded systems needing isolated serial data transmission

Procurement Notes

Verify the manufacturer designation as Harris Corporation or its successor entities, as corporate acquisitions may affect part sourcing. Confirm the specific suffix 'ACB' corresponds to the commercial temperature grade and PDIP package variant. Ensure compatibility with existing PCB footprints for 24-pin DIP configurations before procurement.

Selection Notes

Select this component when a quad RS-232 transceiver is required for single-supply operation. It is suitable for designs needing multiple serial ports without external voltage generation circuits. Consider the 120 kbps speed limit and commercial temperature range when evaluating against higher-performance alternatives.

Part Context

This component belongs to the family of RS-232 line drivers and receivers. It serves as a bridge between TTL/CMOS logic levels and RS-232 signal levels. The quad configuration allows for handling multiple serial lines within a single integrated circuit, reducing board space compared to discrete solutions.
