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 /OE will set all outputs to

the off condition, regardless of any other input conditions.

When the /OE is low, the outputs depend on the state of

their respective latches.
