Verification of AND Gate Function:
1.
Using the SN74HC08 datasheet, complete the schematic in Figure 1 by filling in the pin numbers
for š¯‘‰ , GND, and one of the AND gates.
2. Assemble the circuit shown in Figure 1 on the Digital Trainer and complete the truth table
shown in Table 1.
3. Have the instructor verify your work and initial your results.
