54ACTQ574  
Quiet Series Octal D Flip-Flop with TRI-STATE® Outputs  
General Description  
Features  
n ICC and IOZ reduced by 50%  
The ACTQ574 is  
a high-speed, low-power octal D-type  
flip-flop with a buffered Common Clock (CP) and a buffered  
common Output Enable (OE). The information presented to  
the D inputs is stored in the flip-flops on the LOW-to-HIGH  
clock (CP) transition.  
n Guaranteed simultaneous switching noise level and  
dynamic threshold performance  
n Inputs and outputs on opposite sides of the package  
allowing easy interface with microprocessors  
n Functionally identical to the ACTQ374  
n TRI-STATE outputs drive bus lines or buffer memory  
address registers  
n Outputs source/sink 24 mA  
n Faster prop delays than the standard ACT574  
n 4 kV minimum ESD immunity  
ACTQ574 utilizes Quiet Series technology to guarantee  
quiet output switching and improve dynamic threshold per-  
formance. FACT Quiet Series features GTO output con-  
trol and undershoot corrector in addition to a split ground bus  
for superior performance.  
The ACTQ574 is functionally identical to the ’ACTQ374 but  
with different pin-out.
