WebActive 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 held at ... WebOct 17, 2024 · The logic levels are Low: 0 V to 1/3 VDD and High:2/3 VDD where VDD is the supply voltage. This information can be found here. So, if your processor is designed to operate at 5 volts and is likely made of CMOS logic gates, the low level voltage is from 0 to 1.67 volts and the high level voltage is from 3.33 to 5 volts.
