NOTE 4: 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.
† For conditions shown as MIN or MAX, use the appropriate values specified under recommended operating conditions.
‡ All typical values are at VCC = 5 V, TA = 25°C.
§ Not more than one output should be shorted at a time.
