With a 1 ns typ Tpd, you'd think it would go a bit faster. [snip]
This is as fast as 10KH ECL, at a fraction of the price and hassle.
Incidentally, I ordered the free OnSemi tiny logic ("MiniGate")
sample kit. It arrived in about two days and included over 600 (!)
sample parts. But they're not as fast, more in the 3 ns range.
I swear, being a circuit designer these days is like being a kid
in a candy shop with a $100 bill.
Yes On Semi's kit is truly amazing. Not only for its complete
selection and the generosity of cute little parts, but for its
elegant design and layout.
Many companies are getting on the single-gate bandwagon now. My
only question, why did it take them so long? These are the parts
I needed 25 to 30 years ago!
Perhaps because back then, the chips weren't being pushed aside in
favor of an ASIC that would do the same thing multiple times.
Nowadays the chipmakers have to concede to the designer's needs in
order to get more sales. Or maybe any sales at all?
Or perhaps back then the PC board assembly wasn't as highly automated?
It would be kind of difficult and labor intensive if all those teensy-
weensy chips had to be tweezed into place by hand.
