ELECTRICAL CHARACTERISTICS (continued)

(VBATT = 1.2V to 5.5V, VCC = 1.2V to 5.5V, TA = -40°C to +85°C, unless otherwise specified. Typical values are at TA = +25°C.) (Note1)

Note 1: Production testing done at TA = +25°C; limits over temperature guaranteed by design only.

Note 2: The device is powered up by the highest voltage between VBATT and VCC.

Note 3: MR input ignores falling input pulses, which occur within the MR debounce period (tDEB) after a valid MR reset assertion.

This prevents invalid reset assertion due to switch bounce.
