At one time Tayda was selling TL072CP for about a penny less than TL071CP. So I was thinking, actually, you were robbed!
But nowadays the TL071CP is $0.49 and the TL072CP is $1.99 (!!!).
And the TL074CN is $0.59.
Anyway, obviously whoever packaged and labeled the chips you got either doesn’t know or doesn’t care about the difference, or just has lousy quality control.
Is it just me, or does the logo on that chip look like someone giving you the finger?
Added: Found this for what it’s worth
Same logo and same “21AVNVM” marking but marked TL072CP.
