What is enable in logic gates?
The enable of an AND gate is high active. That is, when the enable is high the input signal will appear on the output. When the AND gate enable input is low, the output will remain a constant low signal. A two input OR gate can also be used with one input the desired signal and the other input is the enable.
What does enable and disable mean?
In simple terms: Enable = To turn On. Disable = To Turn Off. When you turn on a feature you enable it. When you turn a feature off you disable it.
What is enable and disable in electronics?
A Disable will prevent the signal from passing when the control signal is high and will allow a signal to pass when the control signal is low. A Disable is often referred to as an Active Low Enable. When a signal is enabled, the output will match the input.
What is an enable input?
A control input that, when active, permits operation of the integrated circuit and, when inactive, causes the integrated circuit to be in a reduced-power standby mode. NOTE A chip-enable input is a clock or strobe input that significantly affects the power dissipation of the integrated circuit.
What is enable/disable called?
If I’m writing functions that enable or disable something depending some other data, I usually call them “ToggleXXX”.
Is enable and disable same?
As verbs the difference between enable and disable is that enable is to give strength or ability to; to make firm and strong while disable is to render unable; to take away an ability of.
What is the difference between unable and disable?
Originally Answered: What is the difference between disable and unable? Disable is a verb and means to perform an action that makes something not able to function. Unable is an adjective and does not involve performing an action. In other words, you can’t “unable” something.
What is the function of an enable in?
In general, enable pin in multiplexers, de multiplexer, decoder and encoder ensures the functioning of the hardware ie “enables” the function of the logic circuit.
Is enable disable?

What is an SR latch?
An SR latch made from two NAND gates. An SR latch (Set/Reset) is an asynchronous device: it works independently of control signals and relies only on the state of the S and R inputs. SR latches can also be made from NAND gates, but the inputs are swapped and negated. In this case, it is sometimes called an SR latch.
What is the function of enable and disable in logic gates?
Enable and disable typically controls the outputs of the logic gates. When the output is disabled, the output pin is typically high impedance. When it is enabled, it operates normally. This is done to allow outputs of different devices be connected together as in a bus or to perform an additional logical operation.
What happens when the enable input of an OR gate is low?
The enable input of an OR gate is low active. This means that the output will be a copy of the input signal when the enable is low. When the enable input of an OR gate is high, the output of the gate will be a constant high signal. Many different types of logic gates are available on integrated circuits (ICs).
What is a logical gate?
Logic gates are small digital electronic devices that perform a Boolean function with two inputs and provide an output. The data are the binary ones. Logical 1 is true or high, and logical 0 falls to false or low. Based on the logical gate, the logical operation differs, and the output varies.
What is the inhibitor terminal in a logic gate?
The inhibitor terminal S is also sometimes called strobe input or enable input. The bit s = 0 enables the gate to perform the AND logic and thus this bit S = 0 forms the enable input.
