It is ideal for low power, battery operated and low noise 3.3V applications. This 8 bit D-Type flip-flop is 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 Figure 1: Pin Connection And IEC Logic Symbols 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. Power down protection is provided on all inputs and 0 to 7V can be accepted on inputs with no regard to the supply voltage. This device can be used to interface 5V to 3V. It combines high speed performance with the true CMOS low power consumption. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
