Other Parts Discussed in Thread: ULN2003B
Hi guys,
about 6 months ago I was considering the ULN2003B for a new design, but with my surprise I’m seeing now that the ULN2003B is not more active, and the suggested alternative product is the ULN2003AI.
From the data sheet I can see that the ULN2003AI has five times max collector leakage current than the ULN2003B (Icex), 50 µA instead of 10 µA @ 25 °C or 100 µA instead of 20 µA @ 105 °C.
My application is very sensitive to this leakage current and I can’t use the ULN2003AI considering this maximum condition.
There is some characterization of Icex for the ULN2003AI with its inputs stable tied to ground and with VCE to max 13/15 V with the temperature at maximum 40/60 °C? This characterization could help me to reconsidering the ULN2003AI device in our design.
Thank you
Stefano Molinari
