I am interesting in using the HCC4051B multiplexer in my design. However, I can't seem to find a good datasheet that describes the pin outs, and functionality.

I am interested in using this part due to it's radiation tolerances. However, the datasheet posted online only explains the radiation and package specifics. There isn't anything describing the pin out and function of the part. Can someone forward it to me? Or point me to where it's located.
