74HC374 DATASHEET PDF

The output enable OE controls the 3-state outputs and is independent of the register operation. The and are identical in function and differ only in their pinout arrangements. The suffixes 96 and R denote tape and reel. Users should follow proper IC Handling Procedures.

On the positive transition of the clock, the Q outputs will be set to the logic state that were setup at the D inputs HC or their complements HC While the OE input is low, the eight outputs will be in a normal logic state high or low logic level , and while high level, the outputs will be in a high imped- ance state.

The output control does not affect the in- ternal 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 application engineer has a choice of combination of inverting and non-in- verting outputs. The HC and HC are identi- cal, apart from pin layout. The 3-state output configuration and the wide choice of outline make bus-organized systems simple. All inputs are equipped with protection circuits against static dis- charge and transient excess voltage.
