Theory
This produces an output which isthe inverse or opposite of the input signal. Therefore
if the input to an inverter is Logic 1 the output will be Logic 0. Figure L1-1 shows the NOT
gate symbols together with its truth table. The NOT gate Boolean expressions is
X = A
Procedure
1.1 Construct the circuit following the Figure L1-2.
1.2 Apply the supply voltage +5V to IC. Apply +5V to input of NOT gate and measure the
output voltage with the multimeter in DC volt range.
Vo= .................................................. V
1.3 Conenct the NOT gate to ground and and measure the output voltage again.
Vo = ................................................. V
