Vin(dc) specifies the allowable dc excursion of each differential input.
Vid(dc) specifies the input differential voltage |Vtr-Vcp| required for switching, where Vtr is the “pure” input level and Vcp
is the “complementary” input level. the minimum value is equal to Vih(dc) -Vil(dc).
Typ condition: typ model, 1.8 V, and 25 °C. Max condition: BCS model, 1.9 V, and 105 °C. Min condition: WCS model, 1.7
V, and -20 °C.
