200MHz Fmax?

I'll remain more impressed with the big lump of silicon helping me type
this message.

How much of that lump can you buy for 24.7 cents, though?

With a 1 ns typ Tpd, you'd think it would go a bit faster. Probably
does in real life. I should test one, but my fastest pulse generator
is only 250 MHz.

I was wondering why it gets SLOWER for fixed 25°C temperature compared
to the whole -40~85°C range for one Vdd range...
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.

Fun, fun, fun...

Glad you like them. In the Spring/Summer of 2000 I redesigned 12 of
the LCX parts for ON-Semi so that they could be manufactured on the
Chartered Semiconductor process line.

Chartered? As in the Singaporean weapons manufacturer? Interesting.

I don't know anything other than the foundry.

Ok Guys, I went to the OnSemi site to order my free sample kit but could
not find it. How do you do that??

I found it, so can you; John L. gave enough information. Consider it a
test, of sorts.

Spehro, you are killing me! I've been thru that dam site and no way. I'm
too old for tests. Let me give you a test, spell your name correctly. No, I
didn't mean that, I just get frustrated.

Maybe I'll make an eval board for these parts. If I do, I'll make a
few extra and let everybody know.

Some company makes a nice board that uses v-grooves so you can snap
them apart. Dozens of little evaluation boards in one easy-to-handle
piece. Unfortunately, v-grooves are not commonly offered by the proto
board places for cheap.

About 50,000 transistors worth :)

But the sterling advantage of the TinyLogic flipflop is that it can't
run Windows.

What's with the maximum clock frequency specs on the '74?

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.
Thanks,

They were available in Japan for YEARS before most had heard of them
on this side of the pond. Like the "digital" transistors with internal
resistors.
