Notes:
1. All typical values are at VCC = 5V, TA = 25°C.
2. The output conditions have been chosen to produce a current that closely approximates one half of the true
short-circuit output current, IOS.
3. With the outputs open, CLK INH and CLK at 4.5V, and a clock pulse applied to the SH/LD input, ICC is measured first
with the parallel inputs at 4.5V, then with the parallel inputs grounded.
