16 Bump micro SMD Package
See NSC Package Number TLA16AAA
20039104
Note:
The actual physical placement of the package marking will vary from
part to part. The package marking “XY” will designate the date code, “TT” is
a NSC internal code for die traceability. Both will vary considerably. L8B
identifies the device.
