SEMICONDUCTOR TECHNICAL DATA

The MC54/74HC573A is identical in pinout to the LS573. The devices are  
compatible with standard CMOS outputs; with pullup resistors, they are  
compatible with LSTTL outputs.  
These latches appear transparent to data (i.e., the outputs change  
asynchronously) when Latch Enable is high. When Latch Enable goes low,  
data meeting the setup and hold time becomes latched.  
The HC573A is identical in function to the HCT373A but has the data  
inputs on the opposite side of the package from the outputs to facilitate PC  
board layout.
