Hi,
You really saved me. I have already start modifying the boards. (50pcs)
I don't know how I did such a mistake. The old circuit was somehow working though but with so many problems.
I really appreciate your help.

Hi All
I used FLUKE 187 multimeter measure the ICC is 1mA, compare the datasheet 40uA is differences
Test condition
VCC=/1CLR=/2CLR=5V
/1PRE=/2PRE=GND=0V
How do I measure max ICC below 40uA?

Hello all,
I would like to know if CD4027BE can be used as a direct replacement for CD4027BCN.
I have put together a simple toggle switch circuit based…
Hi eli,
My name is Emrys and I will be helping you find the best solution for your project.
It sounds like you're looking for a J-K Flip-Flop such as the SN74HC109. This page is a good starting point to look at the options available. In that link…
I looked at some other parts and the typical minimum pulse width is is about 3ns. That would probably be for any pin. I think 500ps pulse width would probably not be reliable.
Yes this part is synchronous. Here is a part that is not but you will still…
Part Number: CD4536B Other Parts Discussed in Thread: TPL5110 , SN74HC112 , SN74LVC1G97 Hi,
I'm trying to use a timer IC to generate a square wave with a period of some seconds and a duty cycle of about 70% (or 30% and then inverting it).
I would…
