The 74LS14 IC Schmitt Trigger Hex Inverter IC belongs to the 74XXYY IC. 74LS14 uses a single power supply to all the triggers and can be used to operate with any TTL based device. These circuits can be easily operated in any environment and can be triggered easily with the slowest input ramps.
What is a Schmitt Trigger Circuit?
A Schmitt Trigger is a comparator-based circuit that gives the output on the basis of the previous gate output. In a Schmitt Trigger, the input value can be analog or digital but the output will be in two forms 1 or 0. Any circuit is convertible to Schmitt trigger by applying a positive feedback system. In a Schmitt Trigger circuit, the threshold is being used to get output. When the value is higher than the threshold the output will be HIGH otherwise it will be considered in the LOW state. These circuits are not only used to convert analog to digital, but it also helps to remove the noise from the signal.
