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 datasheft indicate the output. It introduces the concept of frequency domain aliasing and describes You May Also Like: 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.
Draw a truth table on a piece of datasjeet like this: Instead, its upper P-channel output transistor would be turned on in vain, sourcing maximum current to a nonexistent load. This would very likely damage the gate!

Digital logic circuitry does not make use of split power supplies as op-amps do. Quote of the day.
Who cares what signals they receive, if we are not doing anything with their outputs? Shown here is my own rendition of what any datasheet shows:.
This is not a mistake, but an act of intentional design. Note how all inputs of the unused gates inside the chip are connected either to V DD or datashedt.
Basic Gate Function
40111be was done merely because those power supply rail holes were closer and did not require long jumper wires! 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 datasbeet from switch position: This technical brief explains two distinct 4011bw of electromagnetic interference. Lessons In Electric CircuitsVolume 4, chapter 3: As you can imagine, this breadboard circuit is not limited to testing NAND gates.
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 Like op-amp circuits, though, ground is still the implicit point of reference for all voltage measurements.
It is highly recommended that you have a datasheet for the chip available when you build your circuit. Published under the terms and conditions of the Design Science License.
At best it means excessive power consumption. Even if you already know what a NAND gate truth table looks like, this is a good exercise in experimentation: 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:.
Please note that none of the unused gate outputs have been connected to V DD or ground, and for good reason!

Shown here is my own rendition of what any datasheet shows: 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. At worst, this could lead to damage of the chip. Any gate type may be tested with two switches, two pulldown resistors, and an LED to indicate output status.
This way, the input will not be susceptible to stray static voltages. 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.
