It is ideal for low power and very high speed 1.8 to 3.6V applications it can be interfaced to 3.6V signal environment for both inputs and outputs. These 16 bit D-TYPE flip-flops are controlled by two clock inputs (nCK) and two output enable inputs (nOE). On thepositivetransitionof the (nCK), thenQ outputs will be set to the logic state that were setup at the nD inputs. While the (nOE) input is low, the 8 outputs (nQ) will be in a normal state (HIGH or LOW logic level) and while high level the outputs will be in a high impedance state. Any 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.
