MC100LVEL91屬于集成電路（IC）的轉(zhuǎn)換器電平移位器。由安森美半導(dǎo)體公司制造生產(chǎn)的MC100LVEL91轉(zhuǎn)換器，電平移位器邏輯轉(zhuǎn)換器或電平移位器 IC 可用于在數(shù)字邏輯設(shè)備之間傳遞信息，這些設(shè)備可在不同/不兼容的供電電壓下工作，或可實(shí)現(xiàn)不同的信令方式。例如，可以將需要 5 V 電源的數(shù)字輸出傳感器連接到具有 3.3 V I/O 電源的 FPGA，或者在 CMOS 或 TTL 等單端信令方式與 PECL 或 LVDS 等差分技術(shù)之間進(jìn)行轉(zhuǎn)換。

Why Do We Need Clock Management?

Can you imagine the chaos in our world if our clocks or watches were not synchronized to Greenwich Mean Time? How would trains, buses, and airplanes run on schedule? The miniseries Longitude was the story of a man who made a major technological breakthrough by inventing an accurate clock that could be carried on sailing ships so navigators could accurately calculate longitude and know where the ship was located at any moment in time. Before this, ships ran aground and many people lost their lives due to navigational errors. Even though there are fixed time zone differences throughout the world, all clocks must agree within fractions of seconds for civilization to work orderly and without confusion. Clock accuracy is one of the most important scientific technologies in our world today.
