The 74LV14A provides provides six independent Schmitt Trigger
input inverters with standard push-pull outputs. The device is
designed for operation with a power supply range of 2.0V to 5.5V.
The inputs are tolerant to 5.5V allowing this device to be used in a
mixed voltage environment. The device is fully specified for partial
power down applications using IOFF. The IOFF circuitry disables the
output preventing damaging current backflow when the device is
powered down
