Note 1: Specifications over temperature are guaranteed by design. Production testing at TA = +25°C only.
Note 2: The MR input ignores falling edges that occur within the MR rising debounce period (tDEB) after MR first rises from low to
high (after a valid MR reset assertion). This prevents invalid reset assertion due to switch bounce.
