Identifying mysterious component
Hello everyone, I m trying to identify a no name composant. All I know is:
-It's a 14 pins componant
-It has 3pins "in" connected to the SoC's GPIO (12, 13, 14)
-It has 8pins "out" connected to a unl2803 (eight-channel darlington array)
-It's used to control 2 stepper motors throught the uln2803
I think it is a Shift register but I can't find any with the 3 connexion to SoC on pins 12,13,14. Do you think I'm right? How could I confirm my thoughts? Or even better, does someone know a componant that fit this description?
