Basic Gate Function

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 Draw a truth table on a piece of paper like this:. This was done merely because those power supply rail holes were closer and did not require long jumper wires! Any gate type may be tested with two switches, two pulldown resistors, and an LED to indicate output status. This technical brief explains two distinct types of electromagnetic interference.

Who cares what signals they receive, if we are not doing anything with their outputs? 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. 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. 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: Like op-amp circuits, though, ground is still the implicit point of reference for all voltage measurements.

This would very likely damage the gate! Please note that none of the unused gate outputs have been connected to V DD or ground, and for good reason! You May Also Like: Shown here is my own rendition of what any datasheet shows:.

At worst, this could lead to damage of the chip. Instead, its upper P-channel output transistor would be turned on in vain, sourcing maximum current to a nonexistent load. This makes operation a little more interesting to observe, and has the further benefit of indicating dztasheet a switch fails to close or open by 4011he the true input signal to the gate, rather than forcing you to infer input status from switch position:.

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.

Note how all inputs of the unused gates inside the chip are connected either to V DD or ground. Lessons In Electric CircuitsVolume 4, chapter 3: This way, the input will not be susceptible to stray static voltages.

Quote of the day.

Even if you already know what a NAND gate truth table looks like, this is a good exercise in experimentation: Digital logic circuitry does not make use of split power supplies as op-amps do.

It introduces the concept of frequency domain aliasing and describes Published under the terms and conditions dahasheet the Design Science License.

As you can imagine, this breadboard circuit is not limited to testing NAND gates. 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.

This is not a mistake, but an act of dahasheet design. Draw a truth table on a piece of paper like this: At best it means excessive power consumption.

It is highly recommended that you have a datasheet for the chip available when you build your circuit.
