Get the data sheet for the chip. It will tell you which end is up. Usually there's a notch or circle at one end. If you put that end up with the notch side facing you, pin 1 is the top left pin.
But don't blame me if your chip is different and you just put it in that way and it blows up. You really need to look at the data sheet. we don't even know what chip you're talking about. There are some really smart people here but I don't think any of them are telepathic.
