CD4584 Hex Schmitt Trigger – Datasheet

The CD4584 Hex Schmitt Trigger is a part of the 4000 IC series. The IC offers an array of operatable voltage levels and also offers features such as ESD protection and thermal overload protection. The IC is easy to use and is directly interfaceable with TTL ICs. The CD4584 may be used in place of the CD4069 hex inverter for enhanced noise immunity to “square up” slowly changing waveforms.

What is a Schmitt Trigger?

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.
