HI-3582PQI-10

Specialized ICS Overview

The HI-3582PQI-10 is a 3.3V ARINC 429 terminal integrated circuit manufactured by Holt Integrated Circuits Inc. It interfaces a 16-bit parallel data bus to the ARINC 429 serial bus using CMOS technology. The device features one transmitter and two receivers, each equipped with a 32x32 FIFO buffer. It operates on a single 3.3V supply within an industrial temperature range of -40°C to +85°C. Packaged in a 52-pin PQFP (10x10 mm) surface-mount case, it supports differential signal transmission at data rates up to 100 Kbps.

Specialized ICS Procurement Notes

Verify the package designation matches the 52-PQFP (10x10) specification. Confirm the manufacturer is Holt Integrated Circuits Inc. Ensure the part number suffix indicates the specific variant required for the application. Check for RoHS compliance status if environmental regulations apply. Validate the operating temperature range against system requirements.

Specialized ICS Selection Notes

Select this component when interfacing a microcontroller or FPGA via a 16-bit parallel bus to an ARINC 429 network. It is suitable for applications requiring dual independent receivers with label recognition capabilities. Consider the 52-pin PQFP package constraints for PCB layout. Ensure the design provides appropriate power supply filtering for the 3.3V digital domain.

Specialized ICS Part Context

This device belongs to the HI-3582/HI-3583 family of silicon gate CMOS devices designed for ARINC 429 bus interfacing. It enhances the industry-standard HI-8282 architecture by providing integrated FIFO buffers and analog line receivers. The series is widely used in commercial aircraft and military helicopter programs for reliable data bus communication.

Specialized ICS Replacement Considerations

The HI-3583A serves as a functional alternative within the same family, offering similar terminal capabilities. Verify pin compatibility and FIFO configurations before substitution. Other variants like HI-3582CJI share core functionality but may differ in package or voltage specifications.
