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 3.4V.
3. This parameter is valid for any VCC between 0V and 2.1V, with a transition time of up to 10msec. From VCC = 2.1V to VCC = 5V ± 10%, a
transition time of up to 100
sec is permitted. The ERROR output pin 10 is not included in this spec due to the open collector design.
