74LVC1G14Q
SINGLE SCHMITT TRIGGER INVERTER
Description
The 74LVC1G14Q is an automotive-compliant, single 1-input Schmitt
trigger inverter with a standard push-pull output. The device is
designed for operation with a power supply range of 1.65V 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 I
OFF
. The I
OFF
circuitry disables the
output preventing damaging current backflow when the device is
powered down.
The gate performs the positive Boolean function:

4. Stresses beyond the absolute maximum can result in immediate failure or reduced reliability. These are stress values and device operation should be
within recommend values.
5. Forcing the maximum allowed voltage could cause a condition exceeding the maximum current or conversely forcing the maximum current could
cause a condition exceeding the maximum voltage. The ratings of both current and voltage must be maintained within the controlled range.
