The 74LS02 Quad 2-Input NOR Gate is a 14 pin IC which contains four independent gates each of which performs the logic NOR function. The IC is a dual in - line package whose 14 & 7 no. pin is vcc&gnd, 2 & 3 in and 1 out, 5 & 6 in and 4 out, 8 9 in and 10 out, 11 & 12 in and 13 is out. The package may be through-hole mounted to a printed circuit board or inserted in a socket. Because of DIP package the device is able to perform ideally even at 70 °C.
