TCAN1043HG-Q1: TCAN1043HGDRQ1 Anybody know the marking means?

Hi Wong,

If you go to ti.com, and use the part making lookup tool, you can type in 1043 and it will tell you which packages match that top marking. The First line of letters and numbers is for internal use only and can be used to verify that you are using a genuine TI part.

Best,

Chris
