I was expecting nothing on the output except maybe momentarily ,until I had started the count and it had completed. If I put the manual reset line to Gnd and power up I get a neg on the output. Then gcf4541 will see what is wired wrong. Potentiometer Questions Started by norbss Yesterday at Hcc4541 is how I am using the IC. Not Connected Pin 5. Output to LED through 1k Pin 9.
Hi dr pepper, I see what you mean mate but just tried and still same results. Click here to register now.
Problem understanding HCF4541 Programmable Timer Datasheet
Not Connected Pin Your reset input pin 6 is shown not connected to anything, it will float in this situation causing random resets due to noise. Hi to all, I am trying to build a long interval timer using the HCF IC and am not getting the results I expected, but I am not certain that I am reading the datasheet correctly. Can anyone suggest where I am going wrong?

Please provide a schematic of what you have beside a schematic of the circuit in the datasheet. I think I am reading dagasheet logic and timing tables correctly and that the k, k and 50 pic is all in range? Forums New posts Search forums.
