    Hey There,

    I am brand new to this forum and already love it. 2 mins ago I googled electronics forum and here I am!

    Please excuse my excitement. I have a question regarding schmitt triggers, more specifically the 74HC7014

    The circuit I am replicating only calls for one Schmitt trigger so I do not want to use a whole hex IC. Refer to this thread for the circuit topic (

    Here is the actual schematic I will be breadboarding. As you can see in the top left corner there is the 74HC7014.

    MY QUESTION IS: How can I create a precision schmitt trigger using an op amp?

    According to wikipedia (, I can but am unsure how to go about doing this. Any help is greatly appreciated!

    Or, you could use one of these... TC7SET17FTE85LF or TC7SET17FU,LF. Single gate Schmitt triggers.
