I am looking for transistor arrays for my LED projects as I want to reduce number of components on board. After some searches, I have found that there are two candidates for current source and sink transistor arrays as the following:
UDN2981 : 8 channels high current source MAX 500mA

ULN2003 : 7 channels high current sink MAX 500mA

I will use these transistor arrays for driving large 7-segment display panel , bright led dot matrix panel and other LED projects.
