i'm using L293d(datasheet attached)motor controller for one of my projects.i give input from a 74164 to pin7 of L293d.i gave 5v to both pin8 and pin16 to activate the IC and control motor.i grounded both 4 and 5.i gave the potential from the same set of batteries(5v).to the 74164 and l292d.the circuit worked,but i wanted to give 12V to the pin8.
so i gave +ve terminal of 12v battery to pin8 of L293d.but i dont know where to connect the -ve of the cell.
please help,thank you.
