HI-8590PSI

Overview

The HI-8590PSI is a CMOS integrated circuit designed for ARINC 429 serial bus interfacing, manufactured by Holt Integrated Circuits. It integrates an independent line driver and line receiver within a single package. The device supports data rates up to 100Kbps and operates on a single power supply, typically at 3.3V or 5V. It features high-impedance inputs for reliable signal reception. The component is housed in a 16-pin package and is rated for industrial temperature ranges from -40°C to 85°C. This part serves as a terminal interface for connecting parallel data buses to the ARINC 429 standard.

Feature Summary

• Integrates independent ARINC 429 line driver and receiver functions
• Supports high-impedance input configurations for robust signal integrity
• Operates with single voltage supply compatibility

Applications

• ARINC 429 serial bus terminal interfaces

Procurement Notes

Verify the current lifecycle status before procurement, as the HI-8590PSI is listed as obsolete in several distributor databases. Confirm package availability and lead times with authorized suppliers. Ensure that the specific suffix matches the required operating temperature range and voltage specifications. Cross-reference with official Holt Integrated Circuits documentation to validate pinout and electrical characteristics against system requirements.

Selection Notes

Select this component when a combined transmitter and receiver solution is required for ARINC 429 applications. Consider the 16-pin package constraint and single-supply operation. Evaluate the need for high-impedance inputs versus other interface types. Verify compatibility with the target system's voltage levels and data rate requirements. Check for alternative active parts if long-term supply stability is critical.
