IC2 and IC3 chip numbers : do I have the right ones?

My kit includes ICs labelled :
• M74HC595B1
• M74HC165B1

The labels on the PCB are :
• 74HC595N
• 74LS165N

Do I have the right chips ?

Yep - The important part is the xxxx595 & 165 in this case - particularly if they came with a kit, if you selfsourced you need to check the data sheet if they can handle more than 5v … Anyhow, all parts that come with the kit are vetted & checked, no need to check them all by yourself :slight_smile:

Yes.
