MC74AC373, MC74ACT373  
Octal Transparent Latch  
with 3−State Outputs  
The MC74AC373/74ACT373 consists of eight latches with 3−state  
outputs for bus organized system applications. The flip−flops appear  
transparent to the data when Latch Enable (LE) is HIGH. When LE is  
LOW, the data that meets the setup time is latched. Data appears on the  
bus when the Output Enable (OE) is LOW. When OE is HIGH, the bus  
output is in the high impedance state.
