HI-8586PSI

Overview

The HI-8586PSI is a single-function line driver manufactured by Holt Integrated Circuits, designed for ARINC 429 serial bus applications. It utilizes CMOS technology and features differential outputs to ensure signal integrity in high-noise environments. The device is housed in an 8-pin Plastic DIP (PDIP) package. It operates within a temperature range of -55°C to +125°C, supporting military-grade reliability standards. The component accepts standard inputs and provides robust driving capabilities suitable for avionics data transmission systems.

Feature Summary

• Differential output architecture for enhanced noise immunity
• CMOS technology ensuring low power consumption
• Military-grade wide temperature operation capability
• Compliant with ARINC 429 interface standards

Applications

• ARINC 429 serial data bus transmitters
• Avionics flight control systems
• Engine management interfaces
• Military communication equipment

Procurement Notes

Verify the specific suffix 'PSI' corresponds to the plastic DIP package variant when sourcing. Confirm RoHS compliance status as historical military parts may vary. Ensure the supplier provides traceability documentation required for avionics certification. Cross-reference the manufacturer's current datasheet to validate pinout compatibility with existing PCB layouts before integration.

Selection Notes

Select this component when a single-channel ARINC 429 transmitter is required. Consider the HI-8586CDT if a ceramic DIP package is necessary for higher thermal stability or specific mechanical constraints. Evaluate the HI-3182 series if dual receiver functionality or additional FIFO buffering is needed alongside transmission. Ensure the system design accommodates the required supply voltages specified in the official electrical characteristics table.

Part Context

Holt Integrated Circuits specializes in mixed-signal ICs for aerospace and defense markets. The HI-8586 series addresses the demand for reliable data bus drivers in harsh environments. This part belongs to a family of ARINC 429 compliant devices, offering standardized interfaces for legacy and modern avionics architectures. The company maintains internal design and testing facilities to ensure product consistency.

Replacement Considerations

The HI-8586CDT serves as a ceramic package alternative within the same functional family. Verify pin-to-pin compatibility before substitution. No direct cross-manufacturer equivalents are confirmed in public documentation without detailed electrical parameter matching.
