[sdiy] Are PT2399 delay chips still manufactured?

[Michael Taylor]

Hello,

I spent a couple hours looking for PT2399 delay chips by Princeton
Technology Corporation last night. I was able to find a bunch of "DTC"
bootleg chips and "PTC" chips on Fleabay, Amazon, and Etsy for wildly
different prices. I tried to source them through Mouser and Digikey but
they have no record of the chip.

What is the deal with these chips? Does anyone know of a legitimate source
for non-knock off chips?

Thanks,
Mike
