CD4049 variants

[zener]

I want to build ROG's Double D. It specifies a CD4049UBE but what I have is a CD4049UBCP. Would that make a difference?

Thanks for any help.

Socket it and if it doesn't work I'll send you one. Ti has them for free as samples you know.

Really?    Well, thanks a lot for the offer, I won't decline it if ever. Of course, I always socket ICs and trannies. I hope my chip will works that you don't have to bother sending me one .

The "UB" puts you on the right track.  There will apparently be variation across chips and subcategories, primarily in noise and some sonic qualities, but the critical distinction between buffered ( :cry: ) and unbuffered ( ) seems to be under control.

[Peter Snowberg]

It sould be 100% fine. The UB means unbuffered and the letters after that depend on who made the chip. E=TI code for plastic DIP, CP=Fairchild code for plastic DIP with commercial temperature range.

Take care,

Maybe it's just me, but I think it's funny: 4049 is listed as a "hex inverter buffer", so the 'UB' suffix means an unbuffered buffer...
BTW, you can experiment with any unbuffered inverting-gate chip (NOR, NAND); just tie the inputs (of a gate) together.
Kindest regards, Bernt.

So, what matters is the "U". Actually, what I have is a Motorola MC14049UBCP which has the same name with that of Onsemi.

The buffering in question is with respect to whether it is intended to be followed by a TTL device or not.

I just happen to have 10 CD4049UBE samples coming from TI.

Got a question
Is it possible to ask TI to send samples for the second time? I already got it one time with some ICs, but now I'd like to ask for some different ones...

This is my second sample order, last was in Feb. I ordered some different ones, but I keep hitting them for Burr Brown's each time.

[Kleber AG]

I know nothing about these called "Burr Brown's"  :?  
What difference, and wich ones should I ask then for?
Does they have some ICs for power amplifier? For a high wattage?(around 100W?)

Thanks for the info!
