Functional operation is not implied under these conditions. Exposure to absolute ratings for extended periods of time may adversely affect reliability. Notes: (1) Pins 2, 4, 5 and 7 should be AC-coupled. No external DC bias should be applied. (2) Pin 6 should be AC-grounded and/or pulled to ground through a resistor for current control. (3) Pins 10, 11, 14 and 15 should have no other external bias applied.
