DESCRIPTION
SOT-25
The U74LVC1G14 is a single Schmitt-trigger inverter, it provides
the function Y=A.
The device have different input threshold levels for positive- going
(VT+) and negative-going(VT-) signals because of the Schmitt-trigger
action in the input.
This device has power-down protective circuit, preventing device
destruction when it is powered down.
