When I run that search (which is pretty much the same as the search I gave the URL for earlier), then look at the books that have "TTL" in their titles, none of these titles are TTL related; they're all linear and interface books.
Which makes me wonder where the correct TTL data book in the list of PDFs came from.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
