The integrated circuit grade or temperature grade (or rating) is a method of classifying ICs based on their operating temperature - typically based on the intended purpose of a particular chip .
Components usually fall into one of four categories: commercial, industrial, automative, and military. While commercial-grade are the most commonly sold parts, over the years demand from the military, aerospace, automotive, and exploration (oil/gass) introduced the need for additional rates to satisfy those harsher operating conditions.
Do to their limited availability, military parts are usually much harder to come by - sometimes impossible if a manufacturer has no demand for them.
