In either case, after the clock rises, Q6, Q7, and Q8 are available on their respective output pins. I’m not sure if this is the correct way to do it but I got some results that I don’t understand.

JoeN Edison Member Posts: What does Qn-1 do? The first one was wrong, the 8 input switches should be connected to VDD, not ground.

All bets are off until you debounce the push button driving the clock input – you dataseet be getting anything from 1 to hundreds of edges everytime you press it at datashset moment. Basically I’m duplicating what a MCU does but at very slow speed. I’ve found some code online but unfortunately it is not helpful for understanding how the shift register works. Under these conditions, the chip does not advance these 8 bits at all and SER IN is completely ignored.

JoeN on Oct 09, Here is it in English. What does Q1 Internal mean?

Input s n – LOW 5. I will never ask you to do anything that I wouldn’t do myself. I’ve just updated the datashet image. Mechanical switches should never drive logic clocks directly for this reason!

CD – Q8 output. Input s n – HIGH I did this with one of the 8 inputs and in another test with two inputs simultaneously 3. MarkT on Oct 06, Q7 goes into Q8. According to the output table image CD – Q8 output.

Data Sheet for the CD I thought that the AVR has Schmitt trigger inputs when a port is configured for digital input. I read the truth table simply.

Here’s how I use the switches to duplicate what the MCU does: Have you hit all pins with a logic probe to make sure they have the voltage you think they do? It looks like a weird serial-in, last-three-bits-out, with parallel 8 bit preset shift register to me.

CD – truth table. CD BE – Understanding the truth table.

Clock falling doesn’t do a cd40144, as you would expect. CDBE with buttons and leds Q8. Is this not happening? I did this before with a 74HC shift register and it clarified for me how it functions, but with the CD it’s a different story. That is what the data sheet says, at least.
