Information present at any register is transferred to the
respective latch when the LATCH ENABLE is high (serial-to-
parallel conversion). The latches will continue to accept new
data as long as the LATCH ENABLE is held high. Applica-
tions where the latches are bypassed (LATCH ENABLE tied
high) will require that the OUTPUT ENABLE input be high
during serial data entry.
When the OUTPUT ENABLE input is high, the output
source drivers are disabled (OFF). The information stored in the
latches is not affected by the OUTPUT ENABLE input. With
the OUTPUT ENABLE input low, the outputs are controlled by
the state of their respective latches.
