Note that sinking and sourcing concepts refer to the conventional current flow, which
means current flows from the positive potential towards the negative potential. A sinking
device provides a path to sink current toward ground or to the return path. A sinking device
does not provide power. A sourcing device provides a path that sources current; it
provides a path from the power source. In the following diagram, the device on the right is
the sourcing device, and the device on the left is the sinking device.
