Features  
General Description  
I and I reduced by 50%  
The ACQ/ACTQ373 consists of eight latches with  
3-STATE outputs for bus organized system applications.  
The latches appear transparent to the data when Latch  
Enable (LE) is HIGH. When LE is LOW, the data satisfy-  
ing the input 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.  
CC  
OZ  
Guaranteed simultaneous switching noise level and  
dynamic threshold performance  
Guaranteed pin-to-pin skew AC performance  
Improved latch up immunity  
Eight latches in a single package  
3-STATE outputs drive bus lines or buffer memory  
address registers  
The ACQ/ACTQ373 utilizes Fairchild Quiet Series™  
technology to guarantee quiet output switching and  
improve dynamic threshold performance. features  
GTO™ output control and undershoot corrector in addi-  
tion to a split ground bus for superior performance.  
Outputs source/sink 24mA  
Faster prop delays than the standard AC/ACT373
