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.

With a 12 V supply, CD4000 devices have a drive strength of about 2 mA. With a 3 V supply, they have no guaranteed drive strength at all.
Use a device from a logic family optimized for lower voltages, e.g., SN74LVC112A or SN74HC109.
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?
Other Parts Discussed in Thread: SN74HC109 Looking for low power pulsed edge triggered latches , its mean latch with change detect at the trigger pin , it should be with enable disable pin
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 like…
