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 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 referenced to ground unless otherwise
specified.
Note 3: All typicals are given at VCC = 5V, TA = 25°C.
Note 4: A higher value output capacitor can be used but the “turn-on” and
“turn-off” time will increase proportionally.
