Nor to me!
I pulled out my TI Databook vol 1 (1985) and the diagram in that book is
the same as the 74158 (Page 220 of the new TI book) but the outputs 1Y to
4Y are not inverted for the '157. So that diagram is completely
wrong, but interestingly the truth table is correct. I guess the clue is
that the inputs and outputs from the diagram don't relate to the truth table!
I can scan the pages from my book if you like.
