The datasheet for this part is a bit confusing, so I want to clarify I have the correct understanding of what requirements this part must follow.
The description of this part on the first page advertises that this part has Schmitt trigger inputs, and includes in the application section an example with temperature sensor which makes "the SN74LV4T08-Q1 ideal for the application since it has Schmitt-trigger inputs that do not have input transition rate requirements."
However, there are also a couple of sections of the datasheet (8.3.3 and 9.2.1.2) that stress how important it is that the input transitions between valid logic states quickly in order to reduce excessive power consumption and prevent oscillations. The datasheet even links an application report called "Implications of Slow or Floating CMOS Inputs." The recommended transition rate is 20ns/V.
In my application, I have a slow analog signal connected to one of the inputs of an AND gate in this chip, which has a transition rate closer to 5.4ms/V (something on the order of 270,000x slower than recommended). Am I okay here because of the Schmitt trigger inputs? What is the hysteresis of the Schmitt trigger?
