That was spot on. I suspect it connects to A3. Now there are many many applications and ways to use inverters.

Your schematic is incomplete. In addition, please explain page 1 of 74LS14 Datasheet.

Leading 74la14 to assume floating pins were default LOW. More likely, I think, is that using 4 gates rather than the 2 which would make sense when seen from the point of view of buffering, may well be driven by pcb routing considerations. E enable pin to ground? A trace from Y5 to A3 will almost certainly be entirely under the IC on the top layer, so you can’t see it.

Some important electrical characteristics are the Logic High. Lastly, The first page should always contain the general description of the device to explain what it is. So on the 74lls14they tied Y1 to!

However, the top IC appears 74ls4 be complete in my drawing above. Thus it seems like you miss the A3 input. It also mentions the existence of Hysterisis, if you want to get more into Electromagnetics it is a electric displacement field of a ferroelectric and ferromagnetic material, but translation for this case it “increases the noise immunity and transforms a slowly changing input signal to a fas changing”.

Don’t get me wrong though, all electrical characteristics are there for a reason, and are essential in their own way. And I doubt the delay is important, but I don’t know enough about the motherboard function to be sure. On 74HCxxx High-speed CMOSunconnected inputs are undefined, and can provide either level, or even pick up radio signals or signals from neighbouring traces.

So, if input is Low Logic 0then the 74ps14 will be High Logic 1. If so, seems like it would only be around 50ns or so.

Which I assumed would be LOW. Post as a guest Name. There is at least one connection you’ve missed, which is Y5. The other pins floating came up around 0.

What is it capable of transmitting for Logic 1? I checked it with a continuity tester and sure enough, they are connected. Post as a guest Name. As the 74ls14 is inverting, connecting two inverters in series to remove inversion is sensible and common.

It’s purpose is to invert the signal. Sign up using Facebook. It seems your circuit is incomplete or got pins mixed up.

In fact, I can’t see why the Schmitt Inverter is used at all. Again, based on a purely un-scientific visual inspection.

A small propagation delay would make sense to me. I might just try and dig up the real schematics to make sure I’m not crazy. Why would they do this?

And when I 744ls14 routing, I mean physical routing, actually laying out the traces so that you can connect pin A to pin B. Since this is board-level enable line, I’d guess that the delay is irrelevant.

So even if one manages to do a hard step at the output creating a signal, the step will arrive distorted at input pins mostly the step will be washed outand in case of splitting traces without proper termination, you can even get reflections and get very funny curve shapes 74ks14 high to low or low to high Home Questions Tags Users Unanswered. A3 does indeed connect to Y5.
