4-STAGE PRESETTABLE  
RIPPLE COUNTERS  
TheSN54/74LS196decadecounterispartitionedintodivide-by-twoanddi-  
vide-by-five sections which can be combined to count either in BCD (8, 4, 2, 1)  
sequence or in a bi-quinary mode producing a 50% duty cycle output. The  
SN54/74LS197 contains divide-by-two and divide-by-eight sections which  
can be combined to form a modulo-16 binary counter. Low Power Schottky  
technology is used to achieve typical count rates of 70 MHz and power dis-  
sipation of only 80 mW.  
4-STAGE PRESETTABLE  
RIPPLE COUNTERS  
LOW POWER SCHOTTKY  
Both circuit types have a Master Reset (MR) input which overrides all other  
inputs and asynchronously forces all outputs LOW. A Parallel Load input (PL)  
overrides clocked operations and asynchronously loads the data on the Par-  
allel Data inputs (P ) into the flip-flops. This preset feature makes the circuits

usable as programmable counters. The circuits can also be used as 4-bit  
latches, loading data from the Parallel Data inputs when PL is LOW and stor-  
ing the data when PL is HIGH.
