MIC5891
4.0 APPLICATION INFORMATION
Serial data present at the input is transferred into the
shift register on the rising edge of the CLOCK input
pulse. Additional CLOCK pulses shift data information
towards the SERIAL DATA OUTPUT. The serial data
must appear at the input prior to the rising edge of the
CLOCK input waveform.
The 8 bits present in the shift register are transferred to
the respective latches when the STROBE is high
(serial-to-parallel conversion). The latches will continue
to accept new data as long as the STROBE is held
high. Most applications where the latching feature is
not used (STROBE tied high) require the OUTPUT
ENABLE input to be high during serial data entry.
Outputs are active (controlled by the latch state) when
the OUTPUT ENABLE is low. All outputs are low
(disabled) when the OUTPUT ENABLE is high.
OUTPUT ENABLE does not affect the data in the shift
register or latch.
