(1) All currents into device pins are shown as positive values; all currents out of the device are shown as negative; all voltages are
referenced to ground unless otherwise specified. All values shown as max or min are classified on absolute value basis.
(2) All typical values are V_CC = 5V, T_A = 25°C.
(3) Only one output at a time should be shorted.
