Quiet Series Octal Transparent Latch with TRI-STATE®  
Outputs  
General Description  
Features  
n ICC and IOZ reduced by 50%  
The ’ACQ/’ACTQ373 consists of eight latches with  
TRI-STATE outputs for bus organized system applications.  
The latches appear transparent to the data when Latch En-  
able (LE) is HIGH. When LE is low, the data satisfying the in-  
put timing requirements is latched. Data appears on the bus  
when the Output Enable (OE) is LOW. When OE is HIGH,  
the bus output is in the high impedance state.  
n Guaranteed simultaneous switching noise level and  
dynamic threshold performance  
n Improved latch up immunity  
n Eight latches in a single package  
n TRI-STATE outputs drive bus lines or buffer memory  
address registers  
The ’ACQ/’ACTQ373 utilizes NSC Quiet Series technology  
to guarantee quiet output switching and improve dynamic  
n Outputs source/sink 24 mA  
n Faster prop delays than the standard ’AC/’ACT373  
n 4 kV minimum ESD immunity (’ACQ)  
n Standard Military Drawing (SMD)

threshold performance. FACT Quiet Series  
features  
GTO output control and undershoot corrector in addition to  
a split ground bus for superior performance.
