SN74LVC1G14: SN74LVC1G14 can ignore glitch?

Hello,

The SN74LVC1G14 is a CMOS Schmitt-trigger inverter -- an analog device. It does not "ignore" anything. The input voltage defines the output state.

If you want to filter out pulses of 100ns, then an appropriately sized RC filter can be added to the input of the device to prevent triggering. For example, here's a filter designed to prevent 100ns pulses from triggering the output:

I should note that this is not something that can typically be done with CMOS devices, but because this device has Schmitt-trigger inputs, it is resilient to the slow input edges.
