ELECTRICAL CHARACTERISTICS
The
G
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 the device pins are positive; all currents out of the
device pins are negative.
Note 3:
All typicals are given for V
DD
= 5V, T
A
= 25
°
C.
Note 4:
Guaranteed by design, but not tested.
Note 5:
Short-circuit current does not represent output drive capability.
When the output detects a short-circuit condition, output drive current is
significantly reduced (from hundreds of mA to 20mA max) until the short
is removed.
