WebActive Low. Active Low means that the default signal is at HIGH level. As long as the pin is not pulled LOW, the pin does not become active. Let’s look at this example in Figure 1: Imagine you have an IC with an enable pin. From the overline and the datasheet you find out that this pin is active low pin. This means that as long as this pin is ... WebApr 10, 2024 · The low-side switch is switching ground while the high-side switch is connecting the voltage supply. Generally, you want to keep the ground connected in a circuit and switch the power. One reason is that … WebHIGH is just an alias for the number 1. LOW is just an alias for the number 0. Anywhere you can use numbers you can use HIGH or LOW equally. You can even use them in math: HIGH + HIGH == 2. The same goes for things like INPUT, OUTPUT, RISING, FALLING, etc. They are just aliases to numbers. – plastic containers for breeding fry
