Hey guys, i have a simpe NAND gate chip. its a quad NAND gate HCF4011BE. I have been trying to learn how to use this thing and for interest sake i connected a logic analyzer to the output of the gate. what is strange is the output pin has noise on it when the OUTPUT is low (when the two inputs are high). I have added a pull down resistor on the output pin but the noise is there regardless if i use the resistor or not. What could be the problem?
I cannot upload images for some reason? it just says "uploading" forever. else i would have uploaded a circuit diagram and a screen shot of the logic analyzer
