MOS
technology. It is ideal for low power and very high
speed 1.65 to 3.6V applications; it can be
interfaced to 3.6V signal environment for both
inputs and outputs.
These flip-flops are controlled by two clock inputs
(nCK) and two output enable inputs (nOE).
On the positive transition of the (nCK), the nQ
outputs will be set to the logic state that were
setup at the nD inputs.
While the (nOE) input is low, the 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.The device circuits is
including 26Ω series resistance in the outputs.
These resistors permit to reduce line noise in high
speed applications.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
