HIN207IA

Overview

The HIN207IA is an RS-232 interface integrated circuit manufactured by Harris Corporation, belonging to the HIN207 series. It functions as a transceiver with one driver and three receivers, supporting data rates up to 230 kb/s. The device operates on a single 5 V supply voltage, with a minimum of 4.75 V and a maximum of 5.25 V. It features 15 kV ESD protection and draws 20 mA of operating current. Designed for surface mount installation in SOIC-24 packages, it supports the RS-232 protocol with single-ended receiver signals. The component is rated for an industrial temperature range from -40°C to +85°C.

Feature Summary

• Provides robust signal transmission with high electrostatic discharge protection capabilities.
• Integrates multiple receiver channels within a compact surface-mount package.
• Supports standard RS-232 communication protocols for reliable data exchange.

Applications

• Industrial control systems requiring serial communication interfaces
• Data acquisition equipment needing isolated signal transmission
• Embedded systems utilizing RS-232 connectivity

Procurement Notes

Verify the manufacturer origin carefully, as Harris Corporation's semiconductor assets were acquired by Intersil and subsequently Renesas. Confirm that the specific HIN207IA variant matches the required industrial temperature grade and package type. Check for obsolescence status or lifecycle changes due to corporate restructuring. Ensure compatibility with existing design specifications before procurement.

Selection Notes

Select this component when a single-driver, triple-receiver RS-232 solution is needed for industrial environments. Compare against similar parts in the HIN207 family regarding temperature ratings and pinout compatibility. Consider the availability of alternative sources given the historical ownership changes. Verify that the 230 kb/s speed meets the application requirements.

Part Context

The HIN207IA is part of the broader HIN207 family of RS-232 transceivers originally developed by Harris Semiconductor. This family was known for integrating charge pumps to generate dual supplies from a single 5 V source. Following acquisitions, production continued under Intersil and later Renesas Electronics. The IA suffix typically denotes the industrial temperature range specification.
