They are not meant to imply that device should be op- erated at these limits. The table of “Electrical Characteristics” provide conditions for actual device operation. Note 2:All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to device ground unless otherwise specified. Note 3:All typicals are given for VCC = 5V and TA = 25˚C.
