Notes
2. VIL (min) = 2.0 V for pulse durations of less than 20 ns.
3. TA is the “Instant-On” case temperature.
4. 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.
5. Tested initially and after any design or process changes that may affect these parameters.
