Yep, noob here, sorry about my wallet (ha, beat you to it

)

OK, anyway, I'm doing a PIMETA after a couple of successful CMOYs (thanks Tangent) and as I'm sure you all know, the BUF634P buffer is not available at Digikey or Mouser.

Tangent lists the BUF634U as an alternate, which is available. Same buffer, different package (SOIC-8) right? And I'd need (or want) Browndog adapters for those?

 

[The Monkey]

you can usually find some on ebay.

Try Jameco. Here's the linky:

BUF634P.

They do have some as of..as of right now, anyway (right now being 8:04 PM, PDSTApril 10)

Jameco is our secret "get out of 'no buffer' jail" link.

Sweet, thanks guys.

BrownDogs or you could always do this :

or my fav, this :

^ been doing that to all of my SOICs.

I like that last method. It's...spidery.

 

[Windchill]

Can't even imagine how many ways I could screw that up. Did I mention -- noob?

then my advice, don't even try it out.
i've messed a few SOICs in my early age. part of the learning process.

 

[Sinbios]

I don't like the last method because the pins break very easily. The wire method is the safest.

For future ref..

If you search on TI website, you can see inventory for TI and reported distributor inventory (of course will not have every place.. only those in touch with TI)

The PIMETA also has SO-8 pads on the bottom side for the buffers. The downside of the SO-8 buffers is that they aren't capable of as much output current as the DIP-8 ones, and stacking them is harder.

 

[Windchill]

Thanks everyone for the help. I ordered them (BUF634P) from Jameco -- cheaper than Digikey or Mouser too. And Digikey was showing expected delivery in October. October?!?!

The downside to TI's inventory update is that it is not as up-to-date as it should be. The numbers they show rarely match if you check the current inventory with the seller.

Jameco's DIP-8 BUF634's are not secret anymore, bhjazz! I had mentioned it, too, in the other thread about TREAD and walwarts ("Is a TREAD/STEPS better than a plug pack?"). Maybe I should order some more - I watched them disappear real-time while checking the stock on Newark a few weeks ago. I got enough for my Millett boards that are coming, but I've been thinking about doing Tangent's PIMETA first.

 

[bhjazz]

Well then I hope I didn't just fark up my chances for starting on my Pimeta!

Maybe I'll order mine sooner than I was figuring. Oh well, if I'm too late, I'll just have to spend more time working on casing.

 

[bhjazz]

And a month has passed. Ouch!

Okay, Jameco is fresh out of the BUF634P now. Gonna give them a call Monday to see when the next shipment is.
