Hi ,

I am looking foir a faster replacement for my oscillator chip ( cd4047 ) , I wanna to to up to 2 mhz but this thing is just crappy @ those speeds .

So basicly I need a easy and cheap ttl chip , 14 pins , that can do perfect 50/50 all the time .

I just need a chip # .

May I ask what it will be used for?

Sometimes you can find fast HCT versions of old CMOS I/Cs but the old CMOS CD4047 isn't one of them and peaks out at 100kHz.
