74LS107 (from LMT.RP H442)
Dual J-K-flip-flop
The pinout is not symmetric: notice how the layout is symmetric towards the center, but that stops as it extends towards the outside.
The "73A" might be a reference to the "74LS73A", which is another dual J-K flip-flop. It's possible that the 74LS73 & 74LS107 use the same substrate but different metal layers.
