General Description

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.
