ELECTRICAL CHARACTERISTICS The q denotes specifications which apply over the full operating tempera-
ture range, otherwise specifications are at TA = 25°C. VCC = 5V, VDD = 8V, VEE = – 7V for V.28, – 5.5V for V.10, V.11 (Notes 2, 3)

Note 1: Absolute Maximum Ratings are those beyond which the safety 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.
