Notes:

2.VIL (min.) = 2.0V for pulse durations of less than 20 ns.

3.Typical specifications are the mean values measured over a large sample size across normal production process variations and are taken at nominal conditions (TA = 25° C, VCC). Parameters are guaranteed by design and characterization, and not 100% tested.
