I'm wondering what this IC is used for : J522A SN74LS107AN
I found it (2 actually) and I don't know where it came from. Maybe a computer (that's where I found them).
Datasheet (http://www.ti.com/lit/ds/sdls036/sdls036.pdf (http://www.ti.com/lit/ds/sdls036/sdls036.pdf)) says its called a "flip-flop"? ???
And it only puts out 16 mA max! I'm new to electronics and robotics and the whole shebang, but that's a really small amount, yes?
So if anyone knows what this thing normally does and if there are any fun robotics projects it could be used for, I would greatly appreciate the knowledge.

Hi,

As you found out, it's a flip-flop (bistable multivibrator).
Read up on logic circuits and don't be afraid to Google (https://www.google.com/search?q=flip-flop+tutorial) before asking.
LS is old and very current hungry compared to eg. HC and HCT, so keep them for experiments only - and 16mA is ample for logic.
