SN74LVC1G17: Slow input rise and fall time spec

Part Number: SN74LVC1G17
Other Parts Discussed in Thread: SN74AUP1G17

I use a SN74LVC1G17 to triggle the output voltage of RC circuit.I learned that Schmitt trigger from other manufacturers have limitations on the slope of the input voltage，as shown below. I wonder if there are the same restriction on SN74LVC1G17 as well.

    The LVC devices of all manufacturers are similar.

    There is no limitation. With slow edges, the supply current will increase, but this is still allowed.

    If you want to reduce the power consumption for voltages not above 3.3 V, use the SN74AUP1G17 instead.
