Hi Dana,
Do i receive shorter time because the Vth is low ?
Regards,
I'm not asking about low percent deviation. The question is, if the monoflop is correctly initialized when the pulse starts immediately with Vcc startup? Does the datasheet specify?There is no data on reproducible timing behaviour.
I built 4 identical circuits and measure and receive: 604.23 , 603.39 , 608.99 , 607.3mSec.
The average value is far from calculate delay: 640mSec.
