Driver 2803 does not work for this reason.
 It is made on mosfets. Instead of composite bipolar transistors.Mosfets DO NOT WORK. 2022-496

This is how driver keys should be madeMosfets DO NOT WORK. 2022-494

Driver 2803 does not work for this reason.
It is made on mosfets. Instead of composite bipolar transistors.
It is made with a combination of a buffer and a mosfet.
This seems to me like an smart way to make the simulation much faster than the original "darlington" BJTs configuration.
It doesn't have the exact same electrical characteristics, but I think it is good enough in most cases.

And I think ULN2803 is working now, Mosfets had an error but is already fixed.

What build did they fix it in?
Thank you !
