Octal D-Type Flip-Flop with TRI-STATE® Outputs  
General Description  
Features  
n ICC and IOZ reduced by 50%  
The ’AC/’ACT574 is a high-speed, low power octal flip-flop  
with a buffered common Clock (CP) and a buffered common  
Output Enable (OE). The information presented to the D in-  
puts is stored in the flip-flops on the LOW-to-HIGH Clock  
(CP) transition.  
n Inputs and outputs on opposite sides of package  
allowing easy interface with microprocessors  
n Useful as input or output port for microprocessors  
n Functionally identical to ’AC/’ACT374  
n TRI-STATE outputs for bus-oriented applications  
n Outputs source/sink 24 mA  
The ’AC/’ACT574 is functionally identical to the ’AC/’ACT374  
except for the pinouts.  
n ’ACT574 has TTL-compatible inputs  
n Standard Microcircuit Drawing (SMD)  
— ’ACT574: 5962-89601
