Just ordered a batch of the Motor Driver TB6612FNG and they won't go into negative polarity (CCW .... reverse)

I am quite familiar with H-Bridges and I have been pretty careful about diagnosing this part. If I hold, for example, AI1 High and AI2 Low I will get +vdc on the output. If I reverse these pins I get 0vdc on the output. Exactly the same on the B outputs. In no case can I get -vdc on the Output.

I have a bunch of these modules and have tried three of them so far with the same results. Is it possible that this is a bad batch....or am I doing something wrong?
