Reading Datasheets: Propagation Delay Times (tpLH and tpHL)
AC characteristic #5: Propagation delay times (tpLH and tpHL)
Ideally, an output signal should change immediately in response to changes in an input signal, but there actually is a delay. The time required for an output to change in response to an input change is called a propagation delay time.
