Need Help With A Component(Octal D Flip Flop)
It appears from the data sheet that you should be able to connect it directly presuming you are using the output control pin in a manner that only one component connected to the bus can be selected at any one moment (it specifically states "Due to the large output drive capability and the 3-STATE feature, these devices are ideally suited for interfacing with bus lines in a bus organized system").

The flip flop does not lose data when you toggle the output enable pin.
