It is ideal for low power and low noise 3.3V applications. Information signals applied to D inputs are transferred to the Q outputs on the positive going edge of the CLK pulse. When the CLR input is held low, the Q outputs are held low independently of the other inputs. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
