Looking for 8255 PPI IC |
|
|
Does anyone have any of these around? I'm breadboarding a project and was
tinkering about using this olde, Intel 8255 programable peripheral
interface.
Or does anyone know who sells these?
thanksEd

I think I have a few, condition unknown, from very old motherboards. If you
want to buy them, try www.jameco.com -- they may still have them, even if
not catalog-listed.

I'll take what you got, if resonable. I'm desoldering some ICs from old
mobo's
right now, to save some $$.
thanks

Some 8255A essentially compatibles are still produced and are available
from Digikey/Farnell/RS Components etc.:
CP82C55A, MSM82C55A-2RS, µPD71055C-10, but they are expensive.
These are all alike except that the Harris/Intersil variety (CP82C55A)
will hold the I/O ports to a "1" state after reset, which may be
sometimes useful and sometimes annoying.

There are a lot of older chips in the lates Jameco catalog that I've got in
my mail just yesterday. Almost all of MCS-80/85 is there as well as 6502,
6800 etc. 8255s are in in several flavors and they are not even expensive...

Someone else said Jameco. I gave them a call and now I got some.
Now project time. What kind of project can I make w/ this?
