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. This parameter is valid for any VCC between 0 V and 2.1 V with a transition time of up to 10 msec. For VCC = 2.1 V to VCC = 5 V"10%, a

transition time of up to 100

µsec is permitted.
