Hbridge Circuit output
Pinned out incorrectly - the output is on pin 5 and 7.  Data sheet shows pins correctly, but you must count in a counterclockwise direction starting with pin 1: pin 5 is opposite pin 4 and pin 8 is opposite pin 1.  If you connect the pins properly, and you want to run from a logic level, you will need a gate driver or other circuit to level shift the high side P channel FETs.  The gates must go all the way to the rail to turn off the P channel FET.  For this part, almost any gate driver will be adequate.
