So I've ordered some TL082CDT and TL074CDT from tayda. And I'm clueless about their pinout as there is no indicator on the package for "Pin 1". Anyone got a clue?
The chips look like this: (the numbers below 082C and 074C is different)

The bevelled edge is the indicator, I'm pretty sure it is on the pin 1 side so in both your pictures pin 1 is bottom left. Check the data sheet to be sure.

I just checked the datasheet and it is no help at all. I actually just faced this same question today as I am working on an SMD build and just soldered on the TL074 today. The ones from Tayda do not have the usual markings of direction, so I just kind of guessed :P If it doesn't work when I'm done I will let you know which way is which.

EDIT: rechecked the datasheet. The beveled edge is the pin 1 side. thanks again!
