I bet everyone uses the good old ULN2003, as old as the hills, was it Sprague or Unitrode?
I think the reason for its existence was to drive 24V relays, and it is generously rated at 50V 500mA
Beware - there’s a newcomer on the scene, under the Diodes brand and it’s only rated at 20V.
It blows up on a 24V supply.
Now Diodes does some good stuff, especially the old Zetex (formerly Ferranti) transistors. By all means make a Darlington arrays but don’t call it ULN2003 then rate it at 20V, even with an extra suffix hidden in the part code.
Now after spending all morning searching for the fault, I’ve got two dozen to unsolder. . . .
