AI Thread Summary
The discussion centers on identifying a specific logic symbol on a spec sheet for a digital fundamentals paper, described as a diamond surrounded by four triangles, likely representing transmission gates. Participants clarify that the symbol is associated with latches, which control data flow and output states. Additionally, they explain that VDD and VSS refer to the supply voltage and ground, respectively, and are essential connections for the integrated circuit. The inquiry about the placement of pins 16 and 8 on the spec sheet is addressed, emphasizing that these power and ground pins are integral to the logic diagram. Overall, the conversation provides insights into interpreting logic symbols and their functions in digital circuits.

Hi there

I'm currently doing a digital fundamentals paper and I was wondering if anyone could identify a logic symbol on the spec sheet attached, and what's it used for. It's on page 4, and the logic symbol is a diamond that is surrounded by 4 traingles. Theres eight of them and it's near pins 5, 3, 2, 4, and 1.
Also, where would pins 16 and 8 go on the spec sheet?

Cheers

Guessing here but from the descriptions those are the latches. The load line either allows the current data to flow through (not active) or latches in the previous output (latched case).

Well VDD is your supply voltage and VSS is ground most likely. If you are asking where they would go on the logic diagram they would be all over the places as what you are seeing as logic blocks are made of transistors which require connection to both of those.

They are transmission gates:

And what do you mean by where do Vdd and Vss go on the "spec sheet"? As Floid says, they are the power and ground pins for the IC.
 
Oh right, sorry, don't know what I was thinking when I was typing haha! Thanks a lot!
 
Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...

My water meter is submerged under water for about 95% of the year. Today I took a photograph of the inside of my water meter box because today is one of the rare days that my water meter is not submerged in water. Here is the photograph that I took of my water meter with the cover on: Here is a photograph I took of my water meter with the cover off: I edited the photograph to draw a red circle around a knob on my water meter. Is that knob that I drew a red circle around my meter...
