ELECTRICAL CHARACTERISTICS
The q denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°.
VCC = 5V ±5%, VEE = –5V ±5%, TA = TMIN to TMAX (Notes 2, 3) unless otherwise noted.

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
pins are negative. All voltages are reference to ground unless otherwise
specified.
Note 3: All typicals are given at VCC = 5V, VEE = – 5V, TA = 25°C.
