Hi expert,
My customers have a questions regarding the timing requirements definition of the SN74AHC595. Does the device read the data on the rising edge of the CLK signal, so that the data/SER signal should be set up at least Tsu before the CLK rising up to 50% and hold on at least Th for remaining the status? Am I understand these timing parameters correctly?
What would happen if the CLK is rising upto 50% before the SER is set up (like waveforms below, blue: SER data, green: SCLK)?


BR,
Manu
