PEOPLE Logic Gates Activity
Circuit for the NOT Gate:
NOT Gate
The picture above shows the NOT gate symbol, where the letter A
represents the input and the letter Y represents the output. The pin
configuration of the 7404 NOT Gate IC is shown below:
Fill in the Truth Table below for the NOT gate:
In the pin configuration diagram, circle the pins which are the
inputs, draw a slash through the pins which are the outputs, draw a
star on the positive polarity pin, and draw a triangle on the ground
pin.
Practice with the NOT logic gate:
1) Place the 7404 in the breadboard.
2) Connect Pin7 (GND) to 0V and Pin14 (Vcc) to +5V.
3) According to the circuit shown on the next page, connect the
Input "A" to Data Switch SW4 (or any other switcher of your choice)
and connect the Output "Y" to the LED display.
4) Turn on the power of the ID-800 and turn the Data switch SW4
from "0" to "1" and back to "0", observe the output of the NOT Gate
for each situation, then record it in the table on the next page.
Hints:
1) For all of these exercises, the 0 in the left column(s)
correspond(s) to the situation where the switch is open to
GND, and the 1 in the A column corresponds to the
situation where the switch is open to VCC (+5V).
2) Your answer for each box in the right column will always be
a 0 or a 1. “0” means low voltage (i.e. the LED did not light
up.) “1” means high voltage (i.e. the LED lit up.)
