The output conditions have been chosen to produce a current that closely approximates one half of the true short-circuit output current, IOS.
NOTE 1: With the outputs open, CLK INH and CLK at 4.5 V, and a clock pulse applied to SH/LD, ICC is measured first with the parallel inputs at
4.5 V, then with the parallel inputs grounded.
