Schmitt Trigger Symbol Non Inverting. Inside there is the hysteresis symbol. 74hct2g17 dual non inverting schmitt trigger.
The schmitt trigger circuit can be designed using op amp in two ways. There are basically two symbols for the schmitt trigger. They are capable of transforming slowly changing input signals into sharply defined jitter free output signals.
Depending on the type of schmitt trigger inverting or non inverting standard the hysteresis curve sign differs.
Depending on the type of schmitt trigger inverting or non inverting standard the hysteresis curve sign differs. A symbol of schmitt trigger shown with a non inverting hysteresis curve embedded in a buffer. The documentation for the particular schmitt trigger being used must be consulted to determine whether the device is non inverting i e where positive output transitions are caused by positive going inputs or inverting i e where positive output transitions are caused by negative going inputs. If the input signal is connected at the inverting point of op amp it is known as inverting schmitt trigger.
