Note 3: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. Except for “Operating Temperature Range” they
are not meant to imply that the devices should be operated at these limits. The table of “Electrical Characteristics” provides conditions for actual device operation.
Note 4: These specifications apply for 4.5V ≤ V_CC ≤ 5.5V, −15V ≤ V_CM ≤ 15V and −55˚C ≤ T_A ≤ +125˚C for the DS7820A or 4.75V ≤ V_CC ≤ 5.25V, 0˚C ≤ T_A ≤ +70˚C
for the DS8820A unless otherwise specified. Typical values given are for V_CC = 5.0V, T_A = 25˚C and V_CM = 0V unless stated differently.
Note 5: All currents into device pins shown as positive, out of device pins as negative, all voltages referenced to ground unless otherwise noted. All values shown
as max or min on absolute value basis.
Note 6: Only one output at a time should be shorted.
