outputs will be set to logic states that were setup  
at the D inputs.  
While the OE input is low, the 8 outputs will be in  
a 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.  
Power down protection is provided on all inputs  
and outputs 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.

DESCRIPTION  
The 74VHCT574A is an advanced high-speed  
CMOS OCTAL D-TYPE FLIP FLOP with 3  
STATE OUTPUT NON INVERTING fabricated  
with sub-micron silicon gate and double-layer  
metal wiring C2MOS technology.  
This 8 bit D-Type flip-flop is controlled by a clock  
input (CK) and an output enable input (OE).  
On the positive transition of the clock, the Q  
All inputs and outputs are equipped with  
protection circuits against static discharge, giving  
them 2KV ESD immunity and transient excess  
voltage.
