IC Reference Erased

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.
