Additional Details

The TC74LVX174F contains six master-slave flip-flops with a common clock and clear input. Data is entered into the master sections on the positive-going transition of the clock pulse. The data is transferred to the slave sections on the negative-going transition of the clock pulse. When the clear input is held low, the flip-flops are reset regardless of the other inputs. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
