It is ideal for low power and highspeed 3.3V applications; it can be interfaced to 5Vsignal environment for both inputs and outputs.These 16 bit D-TYPE flip-flops are controlled bytwo clock inputs (nCK) and two output enable in-puts(nOE). On the positive transition of the (nCK),the nQ outputs will be set to the logic state thatwere setup at the nD inputs. While the (nOE) inputis low, the 8 outputs (nQ) will be in a normal state(high or low logic level) and while high level theoutputs will be in a high impedance state.Any output control does not affect the internal op-eration of flip flops; that is, the old data can be re-tained or the new data can be entered even whilethe outputs are off.It has same speed performance at 3.3V than 5VAC/ACT family, combined with a lower powerconsumption.All inputs and outputs are equipped with protec-tion circuits against static discharge, giving them2KV ESD immunity and transient excess voltage.
