SEMICONDUCTOR TECHNICAL DATA  
The MC74LCX573 is a high performance, non–inverting octal  
transparent latch operating from a 2.7 to 3.6V supply. High impedance  
TTL compatible inputs significantly reduce current loading to input drivers  
while TTL compatible outputs offer improved switching noise

performance. A V specification of 5.5V allows MC74LCX573 inputs to be  
I
safely driven from 5V devices.  
The MC74LCX573 contains 8 D–type latches with 3–state standard  
outputs. When the Latch Enable (LE) input is HIGH, data on the Dn inputs  
enters the latches. In this condition, the latches are transparent, i.e., a  
latch output will change state each time its D input changes. When LE is  
LOW, the latches store the information that was present on the D inputs a  
setup time preceding the HIGH–to–LOW transition of LE. The 3–state  
standard outputs are controlled by the Output Enable (OE) input. When  
OE is LOW, the standard outputs are enabled. When OE is HIGH, the  
standard outputs are in the high impedance state, but this does not  
interfere with new data entering into the latches. The LCX573 flow  
through design facilitates easy PC board layout.
