It's a electronic part of the 8-SOIC (0.154, 3.90mm Width) package. A Tube is used to package it. Under normal circumstances, 200MHz is the maximum value. As you can see, it is mounted by Surface Mount. Electronic parts classified as Fanout Buffer (Distribution) are considered to be safety components. When the temperature is set to -40°C~85°C, reliable performance is ensured. Any power source will work, as long as it has 1.14V~1.89VV. As a result, it produces LVCMOS. It is a member of the ICS621 family.
