Hey all;
I'm driving a 2222 transistor with the 5v output high from a 4049 inverter. I'm not sure which figure to refer to on the data sheet regarding how much current I can safely draw from it though. I was hoping to use a 1-3k resistor on the base of the transistor (it's being used as a simple switch).
One of the figures says "Output Drive Current (for 5v supply) -1.6mA (typ.) Another says: "Output Sink Current (for 5v) 6.4mA (typ.)
Which one do I use to decide on my base resistor? Here is a link to the datasheet:
Thanks
