What is the correct part marking for SN74LVC2G74DCU as marked on the part? Datasheet says C74x with x = manufacturing facility. The parts arrive with the marking 74 on top line and CZ on the bottom line. So how do I know I received the correct parts? Should I read the part normally left to right and top to bottom or should I read this starting from bottom left and read counter clockwise? Part markings on this part as well as many others we receive are difficult to match up with the datasheets.
were these free samples or production parts?
they are two reels of production parts about 2500 or so on each reel
