Looking for MC1554G data sheets

[Mostafa Kassem]

The subject says it all. I did the Google and Yahoo thing with no luck.

While we are at it, I am also looking for any info on EP220 power transistor.

TIA.

I have that data book (and I designed the output stage).
Unfortunately my general purpose machine, with the scanner on it, took
a dive this afternoon. PII, ten years old, 400MHz, originally had
Win95 on it, now has Win2K ;-)

So it'll be several days to a week before I have a replacement up and
running :-(

(Right now I'm running off my laptop which has only Eudora, Agent and
PSpice on it

10 year old Pentium II? My 233MHz Pentium is just 6 years old. It's still
alive - I am using it to post this (and to browse the Internet, and to run
small simulations in LTSpice - it has only 64MB RAM and 1.6GB hard drive).

OK, thanks. Most of the hits I got from Google were about your design. One
of them was about you losing a bet to Tom Frederiksen when he was able to
run it at 5W.

Best regards,

(Right now I'm running off my laptop which has only Eudora, Agent and

I managed to get it to boot this AM and am copying all contents across
the network to another machine with a large drive. After I'm safely
backed-up I'll try to figure out why keyboard and mouse no longer
function.

nice AC EMF spike from the cords wrapped around AC lines?
i know that happen to me once.
has a storm near by, afterwards the keyboard, mouse and controlers
for which on the mother board no longer worked but it would boot up
and required no sign in etc..

"MC1554-Data.zip" posted to the S.E.D/Schematics page of my website.

Data book info only, sorry, no Spice model :-(

You're probably better off redesigning to use something
that's currently being manufactured. The Motorola MC1554G
was discontinued years ago. Motorola sold off their semiconductor
business to Freestyle Semiconductor, and they don't make that part.
Even Rochester Electronics, which stocks obsolete parts, doesn't
have it.

Most of the MC1554 era stuff was sold off to Lansdale, who still make
a lot of my golden oldies, the RS232 chip set, the TTL and PECL PLL
parts, and they even still make my very first chip design, the
MC1530/31 OpAmp. But they don't make the MC1554... by today's
standards it's a kludge, once PNPs made it to the monolithic world.

Freestyle (is that what it's called?) got the specialty CMOS. ON
Semiconductor has the jelly bean level CMOS.
