ULN2803A: Logic voltage levels

Part Number: ULN2803A

Hi, 


Good day. I hope you are well. 

Our customer wants to use the ULN2803A ans they need the exact Logic voltage levels. Can you please help us provide logic voltage levels (VIH,VIL,VOH,VOL) for ULN2803A?

Thank you for your help on this. Have a great day. 


Regards,

Cedrick

  • Hi Cedrik,

    ULN2803a is an anlog device, so there really isn't a clearly defined ON that is black and white as it is a Darlington pair. Current is gained. 

    There is some definitions about Von , Ioff/ on where we define where the darlington pair to OFF/ON based on output current, but they are not equivalent to VIL/VIH/VOL/ etc. 

    Best
