HIN238ACP

Overview

The HIN238ACP is a quad RS-232 line transceiver manufactured by Harris Corporation, designed for single-supply operation. It features four drivers and four receivers within a 24-pin PDIP package. The device supports data rates up to 120 kbps and operates on a single 5 V power supply. It functions reliably across an operating temperature range from 0 °C to +70 °C. The component includes integrated charge pumps to generate the necessary voltages for RS-232 communication without requiring external dual supplies.

Feature Summary

• Integrates four independent drivers and four receivers for full RS-232 communication capability
• Operates from a single 5 V power supply using internal charge pump circuitry
• Supports data transmission speeds up to 120 kbps
• Designed for industrial applications with a standard commercial temperature range

Applications

• Industrial control systems requiring serial communication
• Modem interface circuits
• Point-of-sale (POS) terminals
• Medical equipment with serial data links

Procurement Notes

Verify the manufacturer origin carefully, as Intersil acquired Harris Semiconductor's analog portfolio. Ensure the specific suffix 'ACP' corresponds to the correct packaging and temperature grade in current distributor catalogs. Cross-reference the datasheet revision to confirm pinout compatibility with legacy designs.

Selection Notes

Select this component when a quad driver/receiver configuration is required for RS-232 interfaces. It is suitable for designs needing single-supply operation without external voltage converters. Consider the 24-pin PDIP package for through-hole assembly requirements. Verify that the 120 kbps speed meets the system's timing constraints.

Part Context

This part belongs to the HIN232/HIN238 family of RS-232 transceivers originally developed by Harris Semiconductor. These components are widely used in legacy industrial and commercial electronics. The HIN238 variant specifically provides four channels, offering higher integration density compared to dual-channel counterparts like the HIN232.
