PT2272 Supplier - No data version - (3^12 address)

[Old Steve]

Hi all, the title says it all. I'm looking for a supplier of PT2272 remote control decoder ICs in the 'no data' version, (12-bit tri-state address.)
The M4, M6, L4 and L6 versions are easy to find, (6-bit/8-bit address), but not the 12-bit address version. Any help will be greatly appreciated.
Edit: I forgot to add, I'm looking for the PDIP version, not surface-mount.

Finally, after days of searching, I found a supplier of these chips - http://www.utsource.net/search.aspx?keyWords=PT2272

They have all variations from 0 data bits, (12-bit address), to 6 data bits, (6-bit address), in both momentary and latching, PDIP and SOP. US$0.45 each for the PDIP. Only US$4.00 delivery, too.

They have a good range of hard-to-get parts. I also ordered some MN1381-S voltage detector ICs. (I couldn't find them elsewhere either.)
