outputs will be set to logic state that were setup
at the D inputs.
While the (OE) input is low, the 8 outputs will be
in al 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 flop, that is, the old data can be
retained or the new data can be entered even
while the outputs are off.
It has better speed performance at 3.3V than 5V
LS-TTL family combined with the true CMOS low
power consumpion.
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.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.

3.3V applications.
This 8 bit D-Type flip-flop is controlled by a clock
input (CK) and an output enable input (OE).
