Note 1: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The table of “Electrical Characteristics” specifies conditions of actual device operation.
Note 2: Unless otherwise specified, min/max limits apply across the 0˚C to +70˚C temperature range and the 4.75V to 5.25V power supply range. All typical values
are for T
A
= 25˚C and V
CC
= 5.0V.
Note 3: All currents into device pins are shown as positive; all currents out of device pins are shown as negative; all voltages are referenced to ground, unless
otherwise specified. All values shown as max or min are so classified on absolute value basis.
Note 4: All sectors of this quad circuit may conduct rated current simultaneously, however, power dissipation averaged over a short interval of time must fall within
specified continuous dissipation ratings.
Note 5: For operation over 25˚C free-air temperature, derate linearly to 1328 mW

the rate of 16.6 mW/˚C.
Note 6: Datasheet min/max specification limits are guaranteed by design, test, or statistical analysis.
