HI-8448PQIF Description

Short technical summary and product information.

The HI-8448PQIF is an octal ARINC 429 Line Receiver IC manufactured by Holt Integrated Circuits Inc. This component is designed to translate incoming ARINC 429 data bus signals into CMOS/TTL outputs.

It features independent receiver channels and operates from a single 3.3V or 5V supply, utilizing low-power CMOS technology. The ARINC inputs are internally protected to meet DO-160C/D Level 3 lightning protection requirements. Test inputs are available to bypass analog circuitry and force receiver outputs to a specified state for testing purposes.

The HI-8448PQIF is available in a 44-pin plastic Quad Flat Package (PQFP). It is suitable for applications in avionics and data communications requiring ARINC 429 to CMOS/TTL level conversion.
