This device contains two independent positive pulse triggered
J-K flip-flops with complementary outputs. The J and
K data is processed by the flip-flop after a complete clock
pulse. While the clock is LOW the slave is isolated from the
master. On the positive transition of the clock, the data
from the J and K inputs is transferred to the master. While
the clock is HIGH the J and K inputs are disabled. On the
negative transition of the clock, the data from the master is
transferred to the slave. The logic state of J and K inputs
must not be allowed to change while the clock is HIGH.
The data is transferred to the outputs on the falling edge of
the clock pulse. A LOW logic level on the preset or clear
inputs will set or reset the outputs regardless of the logic
levels of the other inputs.
