MC74AC573, MC74ACT573  
Octal Buffer/Line Driver  
with 3−State Outputs  
The MC74AC573/74ACT573 is a high−speed octal latch with  
buffered common Latch Enable (LE) and buffered common Output  
Enable (OE) inputs.  
The MC74AC573/74ACT573 is functionally identical to the  
MC74AC373/74ACT373 but has inputs and outputs on opposite sides.
