I asked a question earlier question, "Is it safe to run Logic ICs at their maximum output current?" asking if it was safe to run logic ICs at their maximum current.
From what I understand, this is not a good idea and instead I should use some sort of 'driver' between my logic system and my displays.
After some searching I found the SN74HC244N however, this only has a maximum output current of 6mA at 5V (unless I'm reading the datasheet wrong). This doesn't seem very high to me for a 'driver' IC.
This got me thinking as to why I would want to use one of these chips as opposed to 8 transistors (which I assume could handle higher currents). Is it just ease of use that they are already in one small package or is there something I'm missing here?
