Quiet Series Octal D Flip-Flop with TRI-STATE® Outputs  
n Guaranteed simultaneous switching noise level and  
dynamic threshold performance  
n Improved latch-up immunity  
n Buffered positive edge-triggered clock  
n TRI-STATE outputs drive bus lines or buffer memory  
address registers  
General Description  
The ’ACQ/’ACTQ374 is  
a high-speed, low-power octal  
D-type flip-flop featuring separate D-type inputs for each  
flip-flop and TRI-STATE outputs for bus-oriented applica-  
tions. A buffered Clock (CP) and Output Enable (OE) are  
common to all flip-flops.  
n Outputs source/sink 24 mA  
The ’ACQ/’ACTQ374 utilizes Quiet Series technology to  
guarantee quiet output switching and improve dynamic  
threshold performance. FACT Quiet Series  
n Faster prop delays than the standard ’AC/’ACT374  
n 4 kV minimum ESD immunity  
n Standard Military Drawing (SMD)  
— ’ACTQ374: 5962-92189  
features  
GTO output control and undershoot corrector in addition to  
a split ground bus for superior performance.
