This is a simulation of the L9110 H-bridge circuit using the DIP8 package.
Vcc (pin 2) and Vcc (pin 3) can be different voltages or both pins connected to the same voltage source. The logic sources and inverters run at Vcc (in this example limited to 5V).
IA high & IB low: forward
IA low & IB high: reverse
Other combinations: stopped
pin 1: OA
pin 2: Vcc2
pin 3: Vcc3
pin 4: OB
pin 5: GND
pin 6: IA
pin 7: IB
pin 8: GND
