The PMOS transistors prevent backdriving current from the signal pins to V
PMOS transistor is turned off when the associated driver is in the low state.
The PMOS transistor prevents backdriving current from the signal pins to V
Active input detection circuit forces Y9-Y13 to the low state after power-on until one of the A9-A13 goes high. See below.
