Note 1: Overtemperature limits are guaranteed by design and not production tested. Devices tested at +25°C only.
Note 2: RESET2 asserts before RESET1 when V CC goes below the threshold for all supply voltage and temperature ranges.
Note 3: CSRT must be connected to either V CC (for fixed RESET2 timeout period) or an external capacitor (for user-
adjustable RESET2 timeout period).
