SEMICONDUCTOR TECHNICAL DATA  
The MC74LCX574 is a high performance, non–inverting octal D–type  
flip–flop 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  
LOW–VOLTAGE CMOS  
OCTAL D–TYPE FLIP–FLOP  
performance. A V specification of 5.5V allows MC74LCX574 inputs to be  
I
safely driven from 5V devices.  
The MC74LCX574 consists of 8 edge–triggered flip–flops with  
individual D–type inputs and 3–state true outputs. The buffered clock and  
buffered Output Enable (OE) are common to all flip–flops. The eight  
flip–flops will store the state of individual D inputs that meet the setup and  
hold time requirements on the LOW–to–HIGH Clock (CP) transition. With  
the OE LOW, the contents of the eight flip–flops are available at the  
outputs. When the OE is HIGH, the outputs go to the high impedance  
state. The OE input level does not affect the operation of the flip–flops.  
The LCX574 flow through design facilitates easy PC board layout.
