5476/DM5476/DM7476
Dual Master-Slave J-K Flip-Flops with Clear,
Preset, and Complementary Outputs
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
transfered 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.
