Absolute Maximum Ratings
(Note 1)
Note 1:
The “Absolute Maximum Ratings” are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum ratings.
The “Recommended Operating Conditions” table will define the conditions
for actual device operation.
Recommended Operating Conditions
Electrical Characteristics
over recommended operating free air temperature range (unless otherwise noted)
Note 2:
All typical values are at V
CC
=
5V, T
A
=
25
°
C.
Note 3:
The output conditions have been chosen to produce a current that closely approximates one half of the true short-circuit output current, I
OS
.
Note 4:
With the outputs open, CLK INH and CLK at 4.5V, and a clock pulse applied to the SH/LD input, I
CC
is measured first with the parallel inputs at 4.5V,
then with the parallel inputs grounded.
