grounding the SN7404

Other Parts Discussed in Thread: SN7404

I'm assembling the SN7404 on a bread board. The instrument requires a supply voltage of 5 V and ground to operate. I have a 5 V dc power supply, therefore would i connect the negative from the power supply to the ground pin on the 7404?

My objective is to invert a pulse from a pulse generator. Would I then connect the outer sheath from the BNC input and inverted output pulse to the common ground on the inverter?

Thanks for your help, 


  • Hi Dan ,
    Usually the last column for every block in the breadboard are connected together and I would suggest connecting the negative terminal into a common ground on the board and run a small wire to your device gnd . In this way , you will have multiple connections options if you want to connect any caps load on output or Vcc too .
