How can i use a common cathode 7segment as a common anode 7segment display

[meecheekoh]

??? i have purchased a wrong 7segment part no.

i have bought els411 instead of els422. the nearest electronics store is a 2.5hours trip from my province and i can't afford to travel that far to purchase a common anode led display.

i am currently working on my project using 7447. could i still use my common cathode led display for my project? if yes, how can i do that? please help..

I suppose you could, if you ran each of the 7447 outputs (a-g) through inverters, if you have some 7404's handy, before the resistors and LEDs.
