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
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
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.
