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 2: Voltage values are with respect to network ground terminal unless otherwise specified. Note 3: The voltage between two emitters of a multiple-emitter transistor. Note 4: The maximum voltage which should be applied to any output when it is in the “OFF” state. Note 5: Both halves of these dual circuits may conduct rated current simultaneously; however, power dissipation averaged over a short time interval must fall within the continuous dissipation rating. Note 6: Unless otherwise specified min/max limits apply across 0˚C to +70˚C range. All typicals are given for VCC = +5V and TA = 25˚C. Note 7: 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.
