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 V
CC
= 5V, T
A
= 25°C.
Note 4:
I

is an external current being sunk into the V
EE
pin.
Note 5:
These specifications apply to the 24-pin SO Wide package only.
