74LS04 NOT Gate IC | IC Datasheet

If both outputs are 1 5V wouldn’t they combined still be 5V? The comment was really more for the OP’s benefit to help him datsaheet out his logic.

So there won’t be a conflict if one output of the is high and the other is low. Woah – that’s neat! You should combine them with some sort of logic function eg ‘Or”And’ or similar. If they’re not both high or low at the same time Sign up using Facebook. And thank you for teaching me how to ask questions here: Can you explain to me why it won’t work?


Is it OK for the output pins to be high? It’s unconventional, but clear what you meant in datassheet question now.

I’m not doubting your answer – I just don’t understand why: You are aware that the 74LS’s outputs are active-low aren’t you? I’m thinking that I can just use a ?

Home Datasheeg Tags Users Unanswered. I have made one – just know that I am a total noob regarding electronics – you’ll probably laugh at my attempt: I had a feeling that this was the case. I’m a noob here.

7404 – 7404 Hex Inverter Datasheet

I don’t think it’ll fry anything, but since s aren’t open-collector gates, if you connect two outputs together and they’re not both high or low at the same time, the output logic level will be undefined and datasneet be guaranteed to be either a 1 or a zero.

Dattasheet the 74LS has active low outputs, the Y0 and Y7 outputs will never both be low at the same time. I will connect two Yx pins to two two separate input pins on the Datashewt.

Is there a free web service where I can make that easily? Email Required, but never shown. Icy 2, 5 Following is the schematic from TI’s data sheet so you can see what’s going on in there, and what logic function do you want to implement? But I’m too lazy to edit, I’m just going to consider that last comment as over-completeness: That is, if one is high and the other is low.


Tut yes, you’re right, forgot the ’06 was inverting.

Tying the two outputs together in this fashion is called a ” wired-or ” or ” wired-and ” depending on the polarity of the signals the latter in this case, because the outputs of the ‘ are active low. Sounds like what I need. Basically if one of them wants to be high and the other wants datasheeh be low, they will compete and force limiting currents through each other, very likely damaging them, because you cannot guarantee in any case that they will go high or low at the same time, since then you’d have to tie both inputs together as well.
