How much power can a 74LS541 provide? Rapid Fire

[+grips03]

How much power can a 74LS541 provide from the Colecovision using the Schottky diode method?

TIs 74LS541 datasheet says 15ma. Which might be enough to provide for a rapid fire adapter for CV controllers. Has anyone tried that?

 

I know 74LS541 is already a high replacement IC in the CV, so might not be worth stressing it out any more than it needs to be. At the same time rapid fire is cool.
