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.
