HI-8592PSI

The HI-8592PSI by Holt Integrated Circuits Inc. is a silicon gate CMOS device designed as a line driver compliant with ARINC 429 bus specifications. It operates from a single +5V supply, with an integrated negative voltage converter requiring only two external capacitors. The device features high-impedance tri-state outputs, enabling multiple line drivers to connect to a common bus.

Key electrical specifications include a 5V single rail supply voltage, digitally selectable rise and fall times, and output resistance options of 5 Ohm or 37.5 Ohm. It also provides a built-in 2,000V minimum ESD protection for logic inputs and supports 5V or 3.3V logic level compatibility.

Available in plastic 14-pin SOIC and 24-pin QFN packages, the HI-8592PSI is suitable for industrial and extended temperature ranges. Lead-free and RoHS compliant options are offered. Applications include avionics data communication and CMOS/TTL to ARINC level conversion.

This line driver is designed for applications requiring robust ARINC 429 communication, such as in avionics systems. Its features facilitate integration into various designs, offering flexibility in output resistance and logic level compatibility.
