Notes:
1. The min. and max. values of the Schmitt-Trigger input voltages track each other over temperature, V
DD
, and
process variations.
2. The device is functional from V
DD
down to V
LV
voltage. The minimum operational V
DD
is determined by the value of the V
LV
voltage at ambient temperature. The V
LV
voltage increases as the temperature decreases.
3. All input pins are tied to GND and all output pins are floating.
