BCD DECADE COUNTERS/  
4-BIT BINARY COUNTERS  
The LS160A/161A/162A/163A are high-speed 4-bit synchronous count-  
ers. They are edge-triggered, synchronously presettable, and cascadable  
MSI building blocks for counting, memory addressing, frequency division and  
other applications. The LS160A and LS162A count modulo 10 (BCD). The  
LS161A and LS163A count modulo 16 (binary.)  
BCD DECADE COUNTERS/  
4-BIT BINARY COUNTERS  
The LS160A and LS161A have an asynchronous Master Reset (Clear)  
input that overrides, and is independent of, the clock and all other control  
inputs. TheLS162AandLS163AhaveaSynchronousReset(Clear)inputthat  
overrides all other control inputs, but is active only during the rising clock  
edge.
