آي سي 7473 (فليب فلوب J-K مزدوج)

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-flops 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 states of the J and K
inputs must not be allowed to change while the clock is
HIGH. Data transfers to the outputs on the falling edge of
the clock pulse. A LOW logic level on the clear input will
reset the outputs regardless of the logic states of the other
inputs
