Hi all, i followed stefan tutorial about input and output ports at this address https://stefan.co/ne...h-bitshift-ics/ My problem id that i can't find 74HC165 component Exists an alternative? i can find 74HC166 but this is synchronous and 74HC165 is asynchronous. Please help me. Thank you

Hi Sparkfun is carrying those: http://www.sparkfun.com/products/9519 With a lot of distributors: http://www.sparkfun.com/distributors If a local distributor doesn't has it on his website you could try to contact them. They probably still can get it for you. Conrad has got them as well: http://www.conrad.de...C-74-HC-165-DIP I'm not sure what it would do with the 166 actually

Hello Dops. I guess your distributor is telling something wrong. The 166 is almost obsolete, instead the 165 is still in production. Refer the sheet. However, they are pretty similar and you may buy it anyway: the hardware wiring differences are minimal. Are you living in Italy? If so, there's plenty of places where to buy without great overcost. Cheers

For most applications it should not matter (regarding synchronous/asynchronous). If it's local, just pick one up and see if it works for you (if i recall correctly what stefan's class does, it should work exactly the same as long as inputs don't change during readout)

Thank you Mario, Stefan W. and Stefan. Mario i don't know how it's real my distributor tell me.. but i don't have reason not belive you DataSheet of 165 and 166 are little different as i can see.. i hope never have problems with connections. Thank you again
