The parameter "Prop. Delay@Nom-Sup" in electronic components refers to the propagation delay at nominal supply voltage. Propagation delay is the time it takes for a signal to travel from the input of a component to the output, typically measured in nanoseconds or picoseconds. The nominal supply voltage is the standard operating voltage specified for the component.This parameter is important because it affects the overall speed and performance of the electronic circuit. A shorter propagation delay means faster signal processing and better overall performance. Designers need to consider the propagation delay at the nominal supply voltage when selecting components for their circuits to ensure proper functionality and meet performance requirements.
