1. By setting OD low, the outputs are disabled and OUT is held high while Complementary OUT is held low.The threshold for Output Disable is 1.4V above VEE.
Output Disable should not be driven above mid supply and during normal operation, should be left floating (use with an open collector or 3-State gate for inter-
facing with standard logic).

1. Output Levels are standard 10K ECL and are fully 100K ECL compatible.
2.Transition times are measured from 20% to 80% of a full 10K ECL level swing.
