Hi Kengo-san,
The difference between the two is ambient operating temperature - ULN2003A is rated for -40 to 70C whereas ULN2003AI is rated for -40 to 105C. The difference in VOH spec is due to the ULN2003AI's wider temperature range.
Thanks,
Patrick
Hi Patrick-san,
Exactly, I understood that temperature ranges are different.
But, according to the datasheet, VOH is different under the same conditions as TA=25.
I'd like to know why this spec is different.

Kengo.
Hi Kengo-san,
Since this is an old device, we haven't recently defined the specifications. However, I believe that the same value for 25C and across full temp was used for extra security - I don't think the internal structure makes a difference.
Thanks,
Patrick
