Hello,

First post,

I am looking for standard performance parameters on 4000 Series, 74HC and 74LS series. I cannot seem to find datasheets/web pagees on these standard familes. I need to compare all series.

If any one has any help or a point in the right direction that would be appreciated.

Thanks
