Description
The 74LVC1GX04 combines the functions of the 74LVC1GU04 and
74LVC1G04 into a single package to provide a device optimized for use
in crystal oscillator applications. This integration produces the benefits of
a compact footprint, lower power dissipation, and stable operation over a
wide range of frequency and temperature.
The device is fully specified for partial power-down applications using I_off at
output Y. This disables the output, preventing damaging backflow current
when the device is powered down.
