Hiya, can anyone help me pick out one of these transistors?
I have a supply that's going to be in the range 7.5-10V.
I want to hook a microcontroller running at 5V to the collector via internal pullup of 5.6K so I can read the pin to tell when the afforementioned 7.5-10V is applied to the base of the transistor, which means I need to fully saturate the transistor with the lowest voltage in that range in order to turn it on and short the pin to ground.
So I'm using the transistor as a switch, and the emitter is tied to ground.
I want to use these ICs with built-in resistors to save board space:

But I'm not seeing the stuff I normally see in transistor datasheets in this one... Can anyone help me identify which parameters I should be looking at and why?
