Hello I am trying to get a high and low output on pin 11 to switch LEDs to identify both positive and negative phase sequence. I have found a circuit online have simulator using Multisim, however am running into error. Pins 14 and 7 have not been included in the schematic, however, pin 14 is for VDD(12V) and 7 is to ground. The simulation wasnt allowing me to put those to power the NAND gate 4011.
