HIN240IN

Overview

The HIN240IN is a full-duplex RS-232 transceiver manufactured by Harris Corporation. It integrates five drivers and five receivers within a single package, supporting data rates up to 120 kbps. The device operates on a supply voltage range of 4.5V to 5.5V and features a receiver hysteresis of 500 mV for noise immunity. It is housed in a 44-pin MQFP (10x10 mm) package and supports an operating temperature range of -40°C to 85°C.

Feature Summary

• Integrates five independent drivers and five receivers for comprehensive serial communication
• Supports full-duplex operation compliant with EIA RS-232E and V.28 specifications
• Includes 500 mV receiver hysteresis to enhance signal integrity in noisy environments

Applications

• Industrial equipment requiring robust serial communication interfaces
• Automated facsimile response systems
• Data acquisition systems utilizing RS-232 protocols

Procurement Notes

Verify the manufacturer origin, as Harris Corporation's semiconductor assets were acquired by Intersil and subsequently Renesas. Ensure the specific part number matches current production status or obsolescence notices from authorized distributors. Confirm package marking accuracy and authenticity through official supplier channels to avoid counterfeit components.

Selection Notes

Select this component when a high-channel-count RS-232 interface is required in a compact form factor. The 44-pin MQFP package suits applications with limited board space. Consider the 120 kbps data rate limit and 500 mV hysteresis for compatibility with existing system timing and noise requirements.

Part Context

The HIN240IN belongs to the HIN200-HIN213 family of +5V powered RS-232 transmitters and receivers. This series was designed to meet EIA RS-232E and V.28 standards, providing reliable interface solutions for legacy and industrial serial communication applications prior to widespread adoption of higher-speed alternatives.
