FUNCTION
Power Supply. Bypass V_DDA with a 0.1µF ceramic
capacitor as close as possible to the pin.
Ground Reference for Side A
Logic Input 1 on Side A. INA1 corresponds to OUTB1.
Logic Input 2 on Side A. INA2 corresponds to OUTB2.
Logic Input 3 on Side A. INA3 corresponds to OUTB3.
Logic Input 4 on Side A. INA4 corresponds to OUTB4.
Internally Connected. Leave unconnected or connect
to GNDA.
Logic Output 1 on Side A
Logic Output 2 on Side A
Active-High Enable for Side A. ENA has an internal
2μA pullup to V_DDA.
Ground Reference for Side B
Active-High Enable for Side B. ENB has an internal
2μA pullup to V_DDB.
Logic Output 4 on Side B
Logic Input 1 on Side B. INB1 corresponds to OUTA1.
Logic Input 2 on Side B. INB2 corresponds to OUTA2.
Logic Output 3 on Side B
Logic Output 2 on Side B
Logic Output 1 on Side B
Power Supply. Bypass V_DDB with a 0.1µF ceramic
capacitor as close as possible to the pin.
