Basic Gate Function
This makes operation a little more interesting to observe, and has the further benefit of indicating if a switch fails to close or open by showing the true input signal to the gate, rather than forcing you to infer input status from switch position: This way, the input will not be susceptible to stray static voltages. This technical brief explains two distinct types of electromagnetic interference.
At best it means excessive power consumption. Draw a truth table on a piece of paper like this: At worst, this could satasheet to damage of datazheet chip.
Lessons In Electric CircuitsVolume 4, chapter 3: As you can imagine, this breadboard circuit is not limited to testing NAND gates.
Any gate type may be tested with two switches, two pulldown resistors, and an LED to indicate output status. Even if you already know what a NAND gate truth table looks like, this is a good exercise in experimentation: Draw a truth table on a piece of paper like this:.
Instead, its upper P-channel output transistor would be turned on in vain, sourcing maximum current to a nonexistent load. It is highly recommended that you have a datasheet for the chip available when you build your circuit.
Shown here is my own rendition of what any datasheet shows:.
Published under the terms and conditions of the Design Science License. It introduces the concept of frequency domain aliasing and describes Digital logic circuitry does not make use of split power supplies as op-amps do. This would very likely damage the gate!

This is not a 4011br, but an act of intentional design. Introduction to Capacitive Touch Sensing In this article, we will take a detailed but not too detailed look at the electrical principles that allow us to detect the presence of a Additional Improvement An dztasheet you might want to make to this circuit is to assign a couple of LEDs to indicate input status, in addition to the one LED assigned to indicate the output.
Note how all inputs of the unused gates inside the chip are connected either to V DD or ground.
4011eb Like op-amp circuits, though, ground is still the implicit point of reference for all voltage measurements. However, the presence of those extra switches and LEDs make it very convenient to expand the circuit and help make the circuit layout both clean and compact.
You May Also Like: Please note that none of the unused gate outputs have been connected to V DD or ground, and for good reason! 40111be here is my own rendition of what any datasheet shows: Quote of the day. In the breadboard illustration, I show all the top inputs connected to V DDand all the bottom inputs of the unused gates connected to ground.

This makes operation a little more interesting to observe, and has the further benefit of indicating if a switch fails to close or open by showing the true input signal to the gate, rather than forcing you to infer input status from switch position:.
Who cares what signals they receive, if we are not doing anything with their outputs? This was done merely because those power supply rail holes were closer and did not require long jumper wires!
