I can't really find a CD74AC164, my store does have the CD74HC164 tho, will this one suffice?


looks quite alright to me, eh
No, its not as good. Look at the "Absolute Maximum Ratings" page of the data sheets for those 2 chips. You will see that the "AC" version has much higher current ratings compared to the "HC" version.
