In digital circuits when: A signal is ‘active low’ means that signal will be performing its function when its logic level is 0. If it’s anactive-low pin, you must “pull” that pin LOW by connecting it to ground. For an active high pin, you connect it to your HIGH voltage (usually 3.3V/5V).Click to see full answer. Just so, what is the difference between active low and active high logic?Active low means the function gets done when input is in low state. Active high means function gets done when input is in high state. If there is a chip which enables the output then there will be a pin CE called chip enable.Subsequently, question is, why is active low preferred? Active LOW always helps eliminate indeterminate states due to improper supply voltages. A genuine reason is that it is easier to pull down a signal than pulling it up. In these cases, it is always preferable that we use Active LOW. For digital circuits, sink current capability is more than source current. Similarly, it is asked, what does active low mean? Active LOW is a term used in the field of digital electronics to describe the required logic state of an integrated circuit (IC) pin that will enable its internal function. Usually, the physical pin provides access to a function within the IC, and changing its state to LOW activates this function.What is active low decoder?This means the output is active low. That just means that when the output is active it has a logic low value, rather than a logic high. That’s why decoder output are typically active low.
