SN74AHC74Q-Q1: SN74AHC74Q-Q1

Part Number: SN74AHC74Q-Q1

What is the MSL level for this part, SN74AHC74QPWRQ1.  I see conflicting information on TI's website.  One listing shows MSL = 1 and then another listing of the same parts shows MSL = 3.

    Hi Glenn,

    These are two different orderable part numbers so its possible for them to have different ratings. If you want MSL level 1 you should use the SN74AHC74QPWRG4Q1 orderable. Might I also suggest using the SN74HCS74QPWRQ1, which is a newer device that will come with better performance, it also has an MSL level 1 rating.
