Dear all,
I am making digital clock on large display, I want to use ULN 2003 and UDN 2981 ICs. I want to drive 12V display. if any one have any idea or suggestoin plz put it forward.
There is a freewheel Pin #10 on UDN 2981, What is the purpose of this pin where it is used inverse bias in most of the circuit? this pin is on ULN 2003 too and in most of the ciruit it is used inversly bias? to what is the function of this pin which is not metioned in data sheet..
regards
