Default why use a darlington sink driver

does anyone here knows why we have to pass positive rectangular pulse to a darlington sink driver??? I'm just wondering why because the output in an oscilloscope is quite different in that of the rectangular pulse I sent to that darlington sink driver. Anyone please share your thoughts. Thanks....

Try posting your circuit, and scope pictures - bear in mind the pulse will be inverted!.
