Need old SHIFTER verssion C025914-38

[ijor]

I need an old version of the SHIFTER chip for research purposes. It has to be this part: C025914-38. C025914-38A is not good for me, neither one of the newer ones like C070713. It could be C025914-20 as well. But that is the very first version of SHIFTER and it is quite rare.

I need it at the US, and because I am traveling it has to arrive in 15 days maximum. I don't mind paying shipping from Europe as long as it is affordable and it is fast enough.

Again, C025914-38A (note the extra "A"), the most common version of Shifter, is not the part I need.

Thanks,

Nope. Only A, and IMP brand is what I have here. Maybe people right there in USA have more chances to spot on it, if it was sold rather there ?

Ok, thanks for looking.

Btw Pera, did you ever tested an IMP Shifter without the added diode?

I placed it in board without diodes and it worked. But that was not some longer test, just tried is it working .

Thanks again. I am suspecting that the IMP version might be incompatible with some demos depending on the board and the presence of the diode. I am been told that later motherboards don't need a diode, but may be because the diode, or some other voltage reduction is integrated on the PCB, don't know.
