svtiss said:Hi I need two outputs with pulses , and time different between them 90 degrees i mean Phase-shift 90degree
any IC or other easy way ??? thanks
svtiss said:they are cmos pulses 15 v its logic , about 48 Hz
___-----____-----____
--___-----____-----___, something like that
Count # Q0 Q1 Q2 Output 1 Output 2
0 0 0 0 0 0
1 1 0 0 0 1
2 0 1 0 1 1
3 1 1 0 1 0
4 0 0 1 0 0 ==> RESET ==> count # 0
That's true but the absolute maximum rating is 18V so running it from 15V continiously won't do it any harm, even if they are slightly higher voltage spikes on the supply line.Roff said:CD4013 is rated at 15V maximum.
My mistake. I just looked at the "features".Hero999 said:That's true but the absolute maximum rating is 18V so running it from 15V continiously won't do it any harm, even if they are slightly higher voltage spikes on the supply line.

Good point, Ken. The Johnson counter obviously needs a 192Hz clock to get 48Hz out.KMoffett said:svtiss,
Is the 48Hz a given, or can you change it to a higher frequency so you can use Ron's counter to get out a 48Hz quadrature?
