I'm on the search for a datasheet for the above IC. It's made by Phillips
and I think it was produced from 1990 onwards and discontinued in 2000 or
thereabouts.
It's an 8 pin DIL (surface mount in this case OM1058T) package and is part

  For replacement of BD609 and BD610(motorola),the compatible pair
are BD909 and BD910(ST Micro).Well, after 1 month of waiting, i
finally got BD909 and BD912.
1.Will it work?

Anybody know where I could find a 30 x 30 peltier effect cooling plate
or some smaller that could be pieced together?
TIA

Has anyone tried this board ?

  I need to identify drivers(i hope they are drivers ?....) for the
Motorola output transistors BD910 and BD909 of my Tandberg TR 2025 MB

output to 4 speakers).I could make out somewhat the markings on

Best Buy opened up a new store last week, so I decided to stop on the
eway home from work and see what they had.  Well, I checked out the
Compact Flash and similar flash memory cards and they've got them, but
there's a price war going on right now with prices dropping like crazy,

Now _That's_ a Transistor!  </Crocodile Dundee>
Seems like it's in demand: 13 bidders want it at this time, with
about 3-1/2 days to go.

Was there ever a 40164? I have a circuit diagram showing it as an 8-bit
shift register, but it is quite possible it was a misprint and it should
really be the 74HC164 which of course does exist, was a descendent from the
74164 TTL version, and IS an 8-bit shift register. Though ...

I have three strings of LED Christmas lights from a company called
Holiday Creations (holidaycreations.com) They sell Fiber Optic

I missed this on TV last night, but a colleague mentioned it; the UK ships
vast amounts of old PCBs to China for reprocessing (I guess it meets the
requirements of ISO14001); the footage included scenes of a guy holding a
PCB over an open fire and using pliers to pull ICs off a ...

Does anyone know where to buy 2SA970, 2SA1358 and 2SC3421 transistors in UK

A lot of safety rules require an interlock, such as a switch on a door or
gate, to shut down equipment when the door is opened. The equipment is not
supposed to restart after a shutdown like this, but require the door be
closed, and some other operation (like a pushbutton) ...

I hope to design an air-core transformer which may operate at 100-500 MHz.
However I found the loss is too high.
Can anybody give me some advices to design air-core transformer?
Thanks a million!

BIOS chip is a H.T. M 11955.
Is there an equivalent IC type 28F..., 29... ?
The chip is dead (burned) and want to try to replace it with a new
chip.
