I am trying to identify this IC (see attached image), the part number is clear enough to know the chip but I couldn't figure out which chip manufacturer from the logo on the IC!
The PN is AHCT244 which is an octal buffer/driver.
One more question, why there are some parts that are...
I have a schematic of a flyback power supply that i am trying to design a pcb for.
But i couldn't find any part number for the transformer in the attached image..
Can someone teach me how to find the right part number for transformers?
Or help me find this particular one with the...
I have a schematic in a pdf format (generated by Altium Designer) which has the below capacitors labeled LEC692.
My first guess was this must be the Part Number but I didn't find it in the "Miscellaneous devices" library!! And also looking into the internet didn't give anything!!
On my previous thread, I really want to find a replacement of a U1 component, now I take a new closer look photo of that component but it have a missing parts of manufacturer code, please help identifying this component.
I have some old electronic components that I got from someone who repaired TV's, radio's...
I assumed these were resistors, but the measured resistance doesn't match with the color code.
For the ones with the brown body (see picture), I have two of them with the color code...
I found an oscillator circuit and there are two parts not identified. IC1 and IC2. The symbol looks to be Zener diodes but There is no value .Would anyone have an idea what they could be?
Please see The schematic ,bottom left corner
Best regards to all,
Came across this IC from my car dash. I believe it to be the microprocessor and need help identify it. The IC in question is the one marked IC15 (the biggest one) in the image below. Additional, would appreciate if anyone could guide me as to finding out the logic stores in the IC.
I am trying to identify a part for replacement, and I can't find the part number or manufacturer anywhere.
On the 3-pin, TO-220 package, there is a picture of two diodes with common anode to the center pin.
The logo is a cursive HB, or perhaps the H is stylized as an F. I can find...
Hello, I need some assistance identifying this smd component on an LCD inverter.
It is marked DK and then QM right below it. I have another identical board which is a newer revision and the same part is marked DK however with QS below it.
My preliminary research on s-manuals seems to indicate...
Found an unrecognized black plastic cylinder (1-3/4 inch long X 3/8 inch diameter) labeled “S-10” in my Dad’s miscellaneous electrical ‘junk’ box. Self-tapping screws approx half inch long protrude slightly out each end. Resistance between the screw tips is 11740 ohms, and there is no concentric...
