Goals of the Lab (1) To study TTL voltage characteristics and their implications for analysis and design. (2) To familiarize the student with the TTL databook. (3) To implement the 74LS00 NAND gate in a circuit and observe its characteristics. (4) To observe how DC offset and higher frequencies affect the NAND gate. (5) To measure propagation time delay. Procedures Step 1: Familiarize yourself with the TTL databook. Step 2: Determine VIH, VIL, VOH, and VOL using the databook. VIH - High-level input voltage = 2 (min) VIL - Low-level input voltage = .8 (max) VOH - High-level output voltage = 3.4 (typ) VOL - Low-level output voltage = 0.25 (typ) Step 3: Breadboard a 74LS00 and connect the input to 5V. Determine the input-output voltage characteristics of the circuit by applying voltages between 0 and 5V and by measuring the corresponding output voltages. Plot the results and compare results to the databook. ABC AB C' F(A,B,C)=AB+C' 000 0 1 1 001 0 0 0 010 0 1 1 011 0 0 0 100 0 1 1 101 0 0 0 110 1 1 1 111 1 0 1
