The SN74LVC1GX04 is optimized for creating a crystal oscillator circuit with a buffered square-wave output. This device is fully specified for partial-power-down applications using Ioff (Y output only). The Ioff circuitry disables the outputs, preventing damaging current back-flow through the device when it is powered down.
The first inverter is used as a linear amplifier for crystal oscillator.
The last three inverters ensure a fast edge square-wave at the Y output.
The only intended device use is to generate a square-wave output using a crystal to set the operating frequency.
