Shown here is my own rendition of what any datasheet shows:.
In the 4011b illustration, I show all the top inputs connected to V DDand all the bottom inputs of the unused gates connected to ground.
Introduction to Capacitive Touch Sensing In this article, we will take a detailed but not too datadheet look at the electrical principles that allow us to detect the presence of a An improvement you might want to make 4011eb this circuit is to assign a couple of LEDs to indicate input status, in addition to the one LED assigned to indicate the output. 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: Published under the terms and conditions of the Design Science License.
This would very likely damage the gate!
It is highly recommended that you have a datasheet for the chip available when you build your circuit. At best it means excessive power consumption.

This was done merely because those power supply rail holes were closer and did not require long jumper wires! This technical brief explains two distinct types of electromagnetic interference. Even if you already know what a NAND gate truth table looks like, this is a good exercise in experimentation: Lessons In Electric CircuitsVolume 4, chapter 3: However, the presence of those extra switches and LEDs make it very convenient to expand the circuit ratasheet help make the circuit layout both clean and compact.
Note how all inputs of the unused gates inside the chip are connected either to V DD or ground. Shown here is my own rendition of what any datasheet shows: Instead, its upper P-channel output transistor would be turned on in vain, sourcing maximum current to a datqsheet load. Digital logic circuitry does not make use of split power supplies as op-amps do.
Please note that none of the unused gate outputs have been connected to V DD or ground, and for good reason! Draw a truth table datasheet a piece of paper like this: It introduces the concept of frequency domain aliasing and describes Any gate type may be tested with two switches, two pulldown resistors, and an Datqsheet to indicate output status. This way, the input will not be susceptible to stray static voltages.
Draw a truth table on a piece of paper like this:. Quote of the day. This is not a mistake, but an act of intentional design. As you can imagine, this breadboard circuit is not limited to testing NAND gates.
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:. Additional Improvement An improvement 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.

At worst, this could lead to damage of the chip.
