NOTES:
8. For dual-supply systems theoretical worst case (VI = 2.4V, VCC = 5.5V) specification is 1.8mA.
9. When testing IIL the Q output must be high. If Q is low (device not triggered) the pull-up P device will be ON and the low resistance path
from VDD to the test pin will cause a current far exceeding the specification.
