Notes:

11. When power is initially turned on, VDD must be within its correct operating range (3.0V to 28V) to guarantee the output sampling. The output state is

valid after the startup time of 10µs typical from the operating voltage reaching 3V.

12. Typical values are defined at TA = +25C, VDD = 12V. Maximum and minimum values over the operating temperature range is not tested in production

but guaranteed by design, process control, and characterization.

13. Maximum and minimum hysteresis is guaranteed by design, process control, and characterization.
