It is ideal for low power applications mantaining high speed operation similar to equivalent Bipolar Schottky TTL. These 8 bit D-Type flip-flops are controlled by a clock input (CK) and an output enable input (OE). On the positive transition of the clock, the Q outputs will be set to the logic state that were setup at the D inputs. While the (OE) input is low, the 8 outputs will be in a normal logic state (high or low logic level) and while high level the outputs will be in a high impedance state.

clock input (CK) and an output enable input (OE). On the positive transition of the clock, the Q outputs will be set to the logic state that were setup at the D inputs. While the (OE) input is low, the 8 outputs will be in a normal logic state (high or low logic level) and while high level the outputs will be in a high impedance state. The output control does not affect the internal operation of flip flops; that is, the old data can be retained or the new data can be entered even while the outputs are off. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
