What is this?

I cant find anything on it. It may have come out of a CRT TV or maybe an amplifier. I just stumbled on it and i kind of want to experiment with it

Looks good to me!

I cant find anything on it.

me neither.....

Haha i thought i uploaded this already....

Hmmm in-house marking. Unless we have a Korea Data Systems member on here the best you could would be to ask the manufacturers directly or hope someone comes along and recognises it.

One site says it's this:

60V Complementary PowerTrench MOSFET

but that's just as a result of the 'nearest match' when searching alldatasheet.com for the answer.... so 'cheating' really....

If it didnt have so many pins i would just start hooking up wires and measure with multimeter but i don't want to damage the chip. If it helps it says" Taiwan F9KC7P1" on the underside.

looks good to me as well

A multimeter won't help. The insides could be 'anything' - literally - and no amount of multimetering would reveal the contents!

There are some 'IC detector' tools around that can decipher unmarked and in-house marked devices but they all assume that they'll have a reference copy in their own memory in the first place and there are none I know of that have copies of 'everything' in them.

Well i guess it really is a mystery then. I may be told told to make a new thread but since i have you all here...
I am having problems with a PIR sensor. I have 7.5v going into it. And the output is going to an LED and then finally to ground with the PIR ground. The output of the sensor is supposed to be 3.3v. Its measuring 0.03v. I am guessing this is the low output but i cant get it to trigger. Ive looked all over. I let it warm up. I messed with the pots. Nothing. I tried another brand new sensor in the same circuit, same result. Im at a loss

Say Feller . . . . .

Remember tearing down any KDS 17 inch " kine-scoop " monitors at any time past circa 2000 A.D. ?

If so . . . . ., looks like you have yourself a very-very dedicated, spare Choma processor and regurgitator chip.

You know what thats it! I did tear down an old computer monitor awhile back. Thats awesome you found it. Great researching thank you!

Based on that schematic diagram the actual 8004 device you have is really an MC141540 - the data sheet

http://pdf1.alldatasheet.com/datasheet-pdf/view/898521/MOTOROLA/MC141540.html

corresponds to the pinout in the schematic Edd shows (nice find BTW <thumbs up>) so all is revealed!

It's an "on-screen display controller"
