As internal signals are only strong enough to drive the internal circuitry connected to them, the buffer provides strong output current drive ability for driving external circuitry.

The function is the typical output used from the 555. It can sink or source up to 100 or 200mA to drive LEDs, perhaps a relay etc. See the datasheet

I googled and found these. That may help you.
The 555 timer IC can be used as an inverting buffer as well.
