CD – truth table. CD – Q8 output. Clock falling doesn’t do a thing, as you would expect. Basically I’m duplicating what a MCU does but at very slow speed.

I will never ask you to do anything that I wouldn’t do myself. Have you hit all pins with a logic probe to make sure they have the voltage you think they do?

JoeN Edison Member Posts: Here’s how I use the switches to duplicate what the MCU does: Mechanical switches should never drive logic clocks directly for this reason! Data Sheet for the CD Here is it in English. I read the truth table simply.


I’m not sure if this is the correct way to do it but I got some results dc4014 I don’t understand. Input s n – LOW 5.

Is this not happening? Input s n – HIGH I did this with one of the 8 inputs and in another test with two inputs simultaneously 3. This is called a “preset” function.

All bets are off until you debounce the push button driving the clock input – you will be getting anything from 1 to hundreds of edges everytime you press it at the moment. It looks like a weird serial-in, last-three-bits-out, with parallel 8 bit preset shift register to me.

JoeN on Oct 09, MarkT Brattain Member Posts: I’ve found some code online but unfortunately it is not helpful for understanding how the shift register datashest. In either case, after the clock rises, Q6, Q7, and Q8 are available on their respective output pins.


CD BE – Understanding the truth table. The first one was wrong, the 8 input switches should be connected to VDD, not ground. Q7 goes into Q8.

CDBE with buttons and leds Q8. MarkT on Oct 06, What does Qn-1 do? Under these cd4104, the chip does not advance these 8 bits at all and SER IN is completely ignored. What does Q1 Internal mean? Datashret to the output table image CD – Q8 output. That is what the data sheet says, at least. I thought that the AVR has Schmitt trigger inputs when a port is configured for digital input.

PE – LOW 6. I’ve just updated the schematic image.

CDBE with buttons and leds. While doing the tests I wrote down the output state of Q8. I did vatasheet before with a 74HC shift register and it clarified for me how it functions, but with the CD it’s a different story.
