Information present at an input is transferred to its latch when the
STROBE is high. A high CLEAR input will set all latches to the output
OFF condition regardless of the data or STROBE input levels. A high
OUTPUT ENABLE will set all outputs to the OFF condition, regardless
of any other input conditions. When the OUTPUT ENABLE is low, the
outputs depend on the state of their respective latches.
