Note 2: All currents into device pins are positive; all currents out of device

pins are negative. All voltages are referenced to ground unless otherwise

specified.

Note 3: All typicals are given at VCC = 5V, TA = 25°C.

The q denotes specifications which apply over the full operating

temperature range.

Note 1: Absolute maximum ratings are those values beyond which the life

of the device may be impaired.
