Condition: all other inputs connected to
ground.
NOTES
If a gate is just used as an amplifying inverter, there are
two possibilities:
• Connecting the inputs together gives simpler wiring, but
makes the device output not completely symmetrical.
• Connecting one input to VDD will give the device a
symmetrical output.
