The MC54/74HCT574A is identical in pinout to the LS574. This device  
may be used as a level converter for interfacing TTL or NMOS outputs to  
High Speed CMOS inputs.  
Data meeting the setup time is clocked to the outputs with the rising  
edge of the Clock. The Output Enable input does not affect the states of  
the flip–flops, but when Output Enable is high, all device outputs are  
forced to the high–impedance state. Thus, data may be stored even when  
the outputs are not enabled.

The HCT574A is identical in function to the HCT374A but has the  
flip–flop inputs on the opposite side of the package from the outputs to  
facilitate PC board layout.
