Hello A Khan

Google reveals nothing. What are these parts.....

For starters:

1. Do they have many legs?
2. What are they used in...like Amplifier, Computer etc. Please state device.
3.What color are they?
4.Three legs and black would suggest maybe some sort of Transistor or maybe a little Mosfet.

Sorry, I forgot to ask how big they are. Please indicate some sort of size info.

Give answers to my questions above and I will know Exactly what they are

Eagerly awaiting details from you.

Good luck,
tvtech

According to these sources, the 533TL2 (transliterated) is probably equivalent to a 74LS14 / 54LS14 hex Schmitt inverter.

A datasheet for the 74LS14 is here:
http://pdf1.alldatasheet.com/datasheet-pdf/view/5652/MOTOROLA/SN54LS14J.html

The other chip will be more difficult to find without more information and a picture.

yes it seem to be hex schmidt trigger and there are various packages:

https://www.eandc.ru/catalog/detail.php?ID=9683
https://www.eandc.ru/catalog/detail.php?ID=19927

but i still have not found anything about 10S25 (10С25). it would be easier if we knew what type of device it is.

Thanks for your post,

10S25 has 8 legs looks like an regulator.

533TL2 has 14 legs and 1HT251 has 14 legs.

Can you tell which of the legs on the 10S25 are power in, power out, and ground? What are its other connections? Are you sure it is not an oscillator or opamp? Are you sure of the number? Could the "1" be a "7."

the 1HT251 is a transistor array
https://www.eandc.ru/catalog/detail.php?ID=553

remember to transliterate letters because Soviets use Kirilic.
this means that your "H" is not H but "N" (Which is Kirilic looks like Latin "H").
this is why above site will return 'no match" if you search for 1HT251 (Latin) but it will find two matches if you search for 1НТ251 (Kirilic).
same goes for T which appears to be the same as Т but while they both represent same letter, it is a different character and enough to not find any matches.
one easy way is to just copy and paste those character from Kirilic text of the page itself.
one you know this, Google will be able to find it too (try to copy and paste 1НТ251 ).

btw "looks like regulator" means nothing to me. regulators can be different devices and they come in variety of packages and configurations. don't you have camera on your computer or phone?
