About this component

Non-inverting Schmitt-trigger buffer with independently editable lower and upper thresholds. The output retains its prior state while the input remains inside the hysteresis band.

Parameters

Hysteresis
3 parameters
ParameterNameDescriptionDefault

VTL

Lower threshold

Input voltage at or below which the remembered input state becomes low.

1.5 V

VTH

Upper threshold

Input voltage at or above which the remembered input state becomes high; must exceed LowerThreshold.

3.5 V

VHIGH

High output voltage

Voltage driven for a defined logic-high output.

5 V

Timing and state
2 parameters
ParameterNameDescriptionDefault

TPD

Propagation delay

Threshold-crossing to output propagation delay.

1n s

INITIAL_STATE

Initial state

Initial remembered input state while IN begins inside the hysteresis band.
