Integrated Circuit St microelectronics reference erased
Integrated Circuit St microelectronics reference erased
(OP)
Hello
can someone tell me which is the reference of an integrated circuit ST with these data:
14 pins.
pin 3 VDC (+ 12V)
pin 12 GND
I think these are:
pin 1 output of an oscillator
pin 13 rising edge pulse oscillator (not duration)
pin 14 of the trailing edge pulse oscillator ""
and the rest of the pins to resistors and capacitors.
The board manufacturer has deleted the reference.
Thanks, Patxi.

Other clues, like the overall function of the circuit board, and the relationship of the IC to the overall card, are what might help crack this mystery.

What does the board do?

Of course I can. I can do anything. I can do absolutely anything. I'm an expert!

Or perhaps you'd better do your own research? It's tedious, I know, but at least you know it's an ST part.
Cheers,

The oscillator ST ?? is the oscillator to 3x CD4017.
Is not a PLD, it is similar to : NE555+CD4098
It is broken and I need the reference to replace it.

If it is a safety device and you tamper with it, you will be in deep shit if an accident happens. Even if you done everything right. Stay out.
