CD Triple 3-input OR Gate
Typical supply pin labeling: I am creating a footprint for QFN28 package and found the following symbols in the datasheet. The tech sheet can be found here: What am I missing? Sign up using Facebook.
It’s telling you the size and shape of the pins. Sign up using Cd4057 and Password.
Home Questions Tags Users Unanswered. In such cases it may be possible to determine that a particular combination of constraints like the above could certainly be met, or in some datzsheet determine that e.

Unfortunately, such graphs often only plot typical performance curves rather than guaranteed ones and would thus not be able to authoritatively answer a question like “If the output needs to stay above 2.

What is the meaning of this drill notation on datasheet PCB drawing? Perhaps your confusion stems from the fact that a higher voltage drop reduces datashedt voltage? Unfortunately, the fact that one batch of chips matches the “typical” performance specifications does not imply that future batches of chips will continue to do so.
Renato Tavares 4. Why would drawing a higher current cause a drop in voltage? Nathan Lutterman 5.
But isn’t the output voltage determined solely by VDD and the logic level vd4075 the output pin? I think my problem is with that causal relationship. What determines which of the 2 lines different lines of values I’ll get?
Some nice data sheets have a graph with multiple curves, including guaranteed maxima and minima.

Email Required, but never shown. If you try to draw more current the output voltage will drop.
I realize that VO is different on both lines 4.
