description  
The 74AC11953 consists of a parallel input, an 8-bit storage register feeding an 8-bit counter, and a 3-state I/O  
which provides parallel count outputs. Both the register and the counter have individual positive-edge triggered  
clocks.  
The function tables show the operation of the counter clock-enable (CCKEN, CCKEN) and output-enable (OE,  
OE) inputs. A register clock-enable (RCK) input is also provided.  
The counter (RCO) input has direct load and clear functions. A low-going RCO pulse will be obtained when the  
counter reaches the hex word FF. Expansion is easily accomplished for two stages by connecting RCO of the  
first stage to CCKEN of the second stage. Cascading for larger count chains can be accomplished by  
connecting RCO of each stage to CCK of the following stage.  
The 74AC11593 is characterized for operation from − 40°C to 85°C.
