NOTE – Timing is representative of a 12.5 MHz clock.
Higher speeds are attainable.
Serial data present at the input is transferred to the shift reg-
ister on the rising edge of the CLOCK input pulse. On succeed-
ing CLOCK pulses, the registers shift data information towards
the SERIAL DATA OUTPUT.
Information present at any register is transferred to the
respective latch on the rising edge of the STROBE input pulse
(serial-to-parallel conversion).
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.
