I would like to reply the current shift register "MM74HC595" to "SN74HC595" and would like to check two questions about "SN74HC595" this part.
1. From the pin define, SN74HC595 is a p2p solution to reply MM74HC595. Am I correct?
2. I would like to know the active state of Qa to Qh. From the reference application in the DS, it seems like Qa to Qh is active high, but MM74HC595 is active low. Please correct me if I am wrong.
