Recently I was given this project to work on and soon afterwards of receiving the pcb boards, I immediately began the manufacturing process of adding all the necessary components to the boards. All was well until I got to the upper chips that BOTH had the numbers SCRATCHED OFF OF THEM!!! I sent "MY BOARD" (The "prototype") to a local engineer to see what he could tell me about them, and the lower was WAS VERIFIED as a "LATCH" as I originally suspected it would be, which I was VERY pleased to hear.
However they gave me a few other numbers for the other chip that did NOT VALIDATE! I tried both numbers that they gave me at Mouser, MCM, Jameco, and Digikey and NONE CAME UP!!! As such, they MUST BE THE WRONG NUMBERS!!!! So as a last resort, I turn to you (The manufacturer) for guidance in this "VAGUE" area!
So here's the numbers that they gave me:
TI 901510
serial number
3758147 or 3750147
(fuzzy as to whether that middle
number is an 8 or a 0)
Pretty certain that THIS ONE IS THE "GATE!" ;)
Do you think you can refer me to someone that may be able to tell me "EXACTLY" which IC this is, or at least give me one that has an EXACT Cross Reference Number on it (the pinout and voltage has to be EXACT as the original IC due to the nature of the project).
Sorry to bother you so close to the holidays with this issue, but I've been waiting for two years to get a hold of the guy that gave them to me and he never responded after repeated attempts to locate him!
Thanks a bunch!
