Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.
These are stress ratings only, and functional operation of the device at these or any other conditions beyond
those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.

NOTE 1: The algebraic convention, whereby the most negative value is a minimum and the most positive is a
maximum, is used in this table. Negative current shall be defined as conventional flow out of a device
terminal. ______
NOTE 2: The pushbutton reset input (PB RST)pin is internally pulled up to V
CC
with an internal impedance
of 40k
. ______
NOTE 3: The pushbutton reset input (PB RST)pin must be held low for a minimum of 20ms to guarantee reset.
NOTE 4: For Subgroups 10 and 11, if not tested, shall be guaranteed to the limits specified in Table 1.
