NOTES:
1. Not more than one output should be tested at a time, and the duration of the test should not exceed one second.
2. This is the increase in supply current for each input at 3.4 V.
3. For valid test results, data must not be loaded into the flip-flops (or latches) after applying the power.
4. This parameter is valid for any VCC between 0 V and 2.1 V with a transition time of up to 10 msec. From VCC = 2.1 V to VCC = 5 V ± 10% a
transition time of up to 100 µsec is permitted.
5. Unused pins at VCC or GND.
