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
