Makers and Making: How to use SN75441ONE

I am trying to figure out how to use an SN75441ONE h-bridge. I have it hooked up as in this image: http://tinypic.com/view.php?pic=2v2dzc9&s=6

Pins 1, 8 and 16 are connected to the positive rail (+5 V). Pins 4,5,12 and 13 are connected to ground. Everything else is left alone. My expectation is that since all the input pins are LOW (here unconnected), the output pins should also be LOW. However, the output pins are all HIGH. What is going on here?

Unconnected pins are 'floating' and aren't reliably either HIGH or LOW.
