They have the same high speed performance of LSTTL combined with true CMOS low power comsuption.
These8-bit D-type flip-flops are controlled by a clock input (CK) and an ouput enable input (OE).
On the positive transition of the clock, the Q outputs will be set to the logic state that were setup at the D inputs (HC374) or their complements (HC534).
While the OE input is low, the eight outputs will be in a normal logic state (high or low logic level), and PIN CONNECTION (top view) while high level, the outputs will be in a high impedance state.
The 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 application engineer has a choice of combination of inverting and non-inverting outputs.
The HC374 and HC574 are identical, 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 discharge and transient excess voltage.
