Stupid newbie needs help

Not open for further replies.
okay, one more tiny question. How do I find the equivelent of logic 1 and 0 in volts? is it just 0v-7.5v =>0 and 7.5v-15v =>1 or what? cause I need to find how much time the condenser takes to be charged until leg12=1.
Thanks for all the help!!! :D

Oh and is there a power-on delay because the capasitor takes so long to charge(34sec) for leg 12 to be (1). That's assuming what I wrote above is correct.
 
4001 is not a schmitt-trigger, the exact value depend from manufacturer. If input voltage slowly increase, the out slowly decrease.See a CMOS datasheet,but i`m sure when Vcc=15V under 4V the out=15V and over 10V the out=0V
