LEOAC244PT-D
Overview
The LEOAC244PT-D is a radiation-hardened octal bus buffer with 3-state outputs specifically designed for Low Earth Orbit (LEO) satellite applications. This device operates within a 2V to 3.6V supply range and features two independently controlled 4-bit elements with non-inverting outputs. It is part of the ST-LEO series, characterized by guaranteed outgassing levels and specific radiation tolerance levels suitable for space environments.
Why Choose This Part
This buffer is SEL-free up to 62.5 MeV.cm2/mg and qualified for a total ionizing dose (TID) of 50 krad (Si), making it significantly more reliable than standard industrial components in space. It features low outgassing (CVCM < 0.1% and RML < 1%) and a whisker-free NiPdAu lead finish to prevent short circuits in vacuum environments.
Applications
Key Specifications
Getting Started
When integrating this part, follow ECSS space engineering standards for PCB assembly and thermal management. Ensure the two 4-bit output enable (G) pins are correctly biased to manage the high-impedance state during system power-up. Evaluation should focus on signal integrity within the 2V to 3.6V operating range while accounting for the 24mA drive capability per channel.
