DM5476

* Alternate Military/Aerospace device (5476) is available.Contact a National Semiconductor Sales Office/Distributor for specifications.

This DM5476 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 trans ferred 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 of DM5476 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.
