4-3-1. Reading Datasheets: Propagation Delay Times (tpLH and tpHL)

AC characteristic #5: Propagation delay times (t(pLH) and t(pHL))

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.
