TPL7407L - the difference between Maximum Output Current Figure.4 and Maximum Collector Current on Figure.8 on the datasheet P6

Hi all

Would you mind if we ask TPL7407L.
We apologize that we keep pestering you again,,,

Could you let us know the difference between Maximum Output Current Figure.4 and Maximum Collector Current on Figure.8 on the datasheet P6?
Are these the same meaning?

Kind regards,

Hirotaka Matsumoto
