ELECTRICAL CHARACTERISTICS
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: All currents into device pins are positive; all currents out of device
are negative. All voltages are referenced to device ground unless otherwise
specified.
Note 3: All typicals are given for VCC = 5V, VDD = 8V, VEE = – 7V for V.28,
– 5.5V for V.10, V.11 and TA = 25°C.
