4 This Activity Sheet Will Study The Ttl Nor Logic Gate The Number Is 74aaaa02 Check To Ensure This Number Is On The 1 (46.65 KiB) Viewed 54 times
4. This Activity Sheet will study the TTL NOR Logic gate. The number is 74AAAA02, check to ensure this number is on the DIP chip you install on bread board. 5. NOTE the pinout is different, Inputs on pins 2 and 3, Output on pin 1. 6. For the purposes of data collection, ONLY record LED status when both o switches are in the full throw position. 7. The 3300 resistor may be replaced with one of greater value. 114 13 11 10 VCC Po GND 7402 Quad 2 Input NOR ocedure for the group: 2) Construct the circuit in the Figure below on your breadboard. VCC 5.0V VCC 5.0V Pin 3 Pin 14 Pin 1 S2 R1 Pin_7 >3300 T" Pin 2 LED1
3) Use the switches to test the operation of the gate. Using the LED as an indicator, fill in the table below for each possible condition. Using the multimeter, measure the value of the voltage at the output of the logic gate, across the resistor and across the LED for each possible condition. الم Pin 2 Voltage Pin 3 Voltage Gate Output Y Input X Input Ya Voltage Pin le VR(330) VLED ܒ܀ ܒܢ ܒ܀ ܒܢ ܒ܀ L ܒܢ ܒܢ t 4) A TTL system does not appear to be working correctly. A technician takes the readings from NOR gate and provides the data in the table below.
