validate and test their design implementation to confirm system functionality.

10.1 Application Information

10.1.1 Basic Comparator Definitions

10.1.1.1 Operation

output logic can be inverted by simply swapping the input pins.

10.1.1.2 Propagation Delay

There is a delay between from when the input crosses the reference voltage and the output responds. This is

called the Propagation Delay. Propagation delay can be different between high-to low and low-to-high input

midpoint of the output.
