Projects to use 74hc14
There are three cases where you can use the 74hc14 IC.
Case 1.
You can use the 74hc14 Ic in situations where you need to convert the sinusoidal signal waveforms into square waves. When using Schmitt trigger gates, you can change a sinusoidal wave or triangular waves into a square wave output.
Case 2.
This second case occurs when you need a logic inverter in your project. The 74hc14 chip contains inverter Schmitt trigger gates which give out an output which is the negated logic input. This property is necessary when getting inverted logic for controllers and digital electronics.
Case 3.
When your project generates too much noise, you need to introduce the 74hc14 IC. Notably, this device operates by eliminating any noise in electronic systems. Therefore, it’s essential since noise causes many errors in digital electronics.

How to use 74hc14?
You should know that each gate can independently function. To test this theory, first, select a single gate. Then, connect the power to the IC. Alongside the energy, provide an analog signal at the input.
(Schematic diagram of 74hc14 in a circuit.)
Once you achieve the connection, you will understand the working principle of the Schmitt trigger gate. The regulation states; the output of the Inverting Schmitt trigger output is low only when the voltage level of the input signal passes the threshold voltage. To clarify, until the moment when the input voltage reaches the threshold voltage, the output voltage will always be high. But, this voltage drops once it gets to the threshold voltage. Further, the output(v) remains LOW until the input(v) falls to a LOW voltage. When this change occurs, the result (v) rises. Notably, this is a continuous and interrupted cycle, provided there’s a power supply to the chip.

74HC14 Switching Time
Switching time is the time delay it takes a gate to provide an output of a given input. Importantly, individual gates take a specific amount of time for changing functions. During this switching, you can detect two types of time delays. These time delays are the fall time and rise time. A time difference occurs between when the device input is high, and the output is low. This type of response is the rise time. It takes about 95ns. Similarly, the time difference between a logic input being low to its output going high is the fall time. This delay also takes about 95ns. Therefore, in available cycles, you will have a total time delay of 190ns. These time delays occur when the chip is operating at higher frequencies. The system experiences noise, trigger-malfunctions, and extensive errors whenever you exceed optimum operating frequency.
