Okay - so here is how I will connect it up. E, Vee and GND will go to the GND on my Arduino. The S0, S1 and S2 will go to the digital pins on my Arduino. Vcc will go to the +5v on my Arduino. The A pin will go to my buzzer which then goes to a 9v battery and then to the A0 pin. The polarity at the A pin or the A0 pin doesn't matter I assume - as you say they are just throughput.
So if I then turn on the correct digital pins for A0, the buzzer should go off...is that correct?
I don't want to use a buzzer long term, but its just a test to see that the Arduino is switching correctly.
thanks for your help
