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, and the duration of the short-circuit should not exceed one second. The SN54165 and SN74165 devices are obsolete and are no longer supplied. |
