there are some Differences between 74HC4046 and HCF4046
Thanks, but I already have 74hc4046, and this one is a little different from HCF4046, for example, Vcc Max input for 74hc is 6volts, but in HCF and also some others, Vcc input max is 20volts.
also, I figured oscillator settings from 74hc4046 datasheet, but it doesn't work in HCF. it oscillates at around 20KHZ.
and yes, it's possible to figure out by experience, but because I need it urgent, I needed some help.
so if anyone can help me, I'd be thankful.
