The MC54/74HC563 is identical in pinout to the LS563. The device inputs  
are compatible with standard CMOS outputs; with pullup resistors, they are  
compatible with LSTTL outputs.  
This device is identical in function to the HC533 but has the Data Inputs on  
the opposite side of the package from the outputs to facilitate PC board  
layout.  
These latches appear transparent to data (i.e., the outputs change  
asynchronously) when Latch Enable is high. The data appears at the outputs  
in inverted form. When Latch Enable goes low, data meeting the setup and  
hold time becomes latched.  
The Output Enable input does not affect the state of the latches, but when  
Output Enable is high, all device outputs are forced to the high–impedance  
state. Thus, data may be latched even when the outputs are not enabled.  
The HC573 is the noninverting version of this function.
