Note:
1. VIL (min.) = −2.0V for pulse durations of less than 20 ns.
2. 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.
3. Tested initially and after any design or process changes that may affect these parameters.
