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 pin 3. 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 interfacing with standard logic).
