This is the minimum voltage required across the pins to
ensure switching between logic states; the
instantaneous voltage on either pin must not exceed the
supply rails; ac ground the unused input to accommodate
single-ended operation

Internally generated
Capacitive coupling required; ac ground the unused
input to accommodate single-ended operation; the
instantaneous voltage on either pin must not exceed
the supply rails
Same as voltage sensitivity but specified as power into a
50 Ω load
Each pin has a 2.5 kΩ internal dc bias resistance
