These 8 bit D-Type Flip-Flop 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 that were setup at the D inputs. While the (OE) input is low, the 8 outputs will be in PIN CONNECTION AND IEC LOGIC SYMBOLS a normal logic state (high or low logic level); when the OE is high the outputs go to the 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. This device is designed to interface directly High Speed CMOS systems with TTL and NMOS components. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
