6262 - ispMACH 4000: What does tPD means?
Definition:
Solution:
tPD is the Propagation delay which is the time required for a digital signal to travel from the inputs of a logic gate to the output.
If all other factors are held constant, the average propagation delay in a logic-gate IC increases as the complexity of the internal circuitry increases. Propagation delay has a direct effect on the speed at which a digital device, such as a computer, can operate.
