Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: All voltage values are with respect to GND.
Note 3: For military temperature range parts, consult the factory.
Note 4: The output pins of BATT ON, LOW
RESET have weak internal pull-ups of typically 3μA. However, external pull-
up resistors may be used when higher speed is required.

Note 5: The external clock feeding into the circuit passes through the
oscillator before clocking the watchdog timer. Variation in the timeout
period is caused by phase errors which occur when the oscillator divides
the external clock by 64. The resulting variation in the timeout period is 64
plus one clock of jitter.
Note 6: The input pins of CE IN, OSC IN and OSC SEL have weak internal
pull-ups which pull to the supply when the input pins are floating.
