Connec t the other input of the s ame NAND gate (Pin 2) to a different s witc h. c . Connec t the output of the NAND gate (Pin 3) to the pos itive lead of an LED. 7. Connec t y our protoboard to the battery . 8. Flip the s witc hes through all c ombinations of binary inputs to verify whether y our c irc uit implements the NAND truth table below. a b F = a NAND b 001 011 101 110 The pic tures below s how s c hematic diagram and an ex ample of wired NAND gate us ing pins 1, 2, and 3. Lab 6 Assignment What to do For the final portion of this lab, y ou will implement an XOR func tion (lik e y ou did in mentor graphic s ), but y ou c an us e only NAND gates s inc e y ou are us ing TTL c hips . You only need one 7400 DIP to implement this . W e provide a c irc uit lay out template for y ou to us e whic h s hows y ou how to build the XOR gate. W e als o provide the truth table for the XOR gate below. a b F = a XOR b 000 011 101 110 What to tur n in Print out the XOR s c hematic and label whic h pins are being us ed for eac h NAND gate. Bring y our protoboard to offic e hours and demons trate that y our XOR gate behaves as ex pec ted. That's it!
