Hello,
Im having an issue with the SN7404 IC. The image bellow shows how it is designed. The R7 Resistor Array is used to pull down the 7407 input, so when the CN7 connector is disconnected, the 7407 should stay low. But, when this circuit is powered up, I am measuring 1.4V on the input pins. Is this normal?
