CMOS 555 for Uglyface

[Samy]

I can´t find this cmos ! I just found the LM555 , is that it ?
Can anyone tell me some references of this cmos timer or tell me where to find it ?
Thanks.

I'm pretty sure that you have what you're looking for. The LM is just a reference to the manufacturer.

i don't think the LM555 is a CMOS. and if i'm right you'll hear it when you put it in your uglyface

  yeah, I think there's a CMOS version of the 555 timer and a non-CMOS version, you probably have the non-CMOS version, it might still work but probably will give a weaker sound or some such...at least that's my understanding, might have my head up my ass, always a possibility...

[reverberation66]

oh yeah, smallbearelec.com has the cmos version.

Yeah, this is one of the first ICs ever developed.  Well before CMOS was around.  It is bipolar, except those that explicitly state they are CMOS.

I used a 7555 in my uglyface they're CMOS versions of the 555 and should be easy to find.
